Malwarebytes won`t install, run or update – How to fix it

If Malwarebytes Anti-malware or any of your security programs won’t install, run or update, then you’ve probably got malware or the effects of malware on the computer (some types of malware will disable Malwarebytes Anti-malware and other security tools).

Malwarebytes Anti-malware or any of your security programs won`t install

Fix 1.1: Before saving Malwarebytes Anti-malware or any of your security programs, rename them first.
Once you have clicked to a download link you will see a Save dialog like below.

Save Dialog - Save As

Change file name mbam-setup.exe to explorer.exe like a screen below.

Save Dialog - Save As - Rename

Then click on Save and save it to your desktop.


Double Click explorer to install the application.

Note: several good names that you can use: explorer.exe, iexplore.exe, firefox.exe, userinit.exe, myapp.exe or use any random name

Fix 1.2: Change Malwarebytes Anti-malware or another security program installation file extension.

You need turn on “show file extensions for known file types” before doing it.

Click Start, then click Computer as shown below.

start menu computer option

This will open a Computer screen.

computer screen

Click to Organize and select Folder and Search options like a screen below.

Remove the checkmark from the checkbox labeled Hide file extensions for known file types and press the Apply button and then the OK button. Now your computer is configured to show file extensions for known file types.

Right-click on an installation file (mbam-setup.exe for Malwarebytes Anti-malware) and select Rename.

rename option

Next, replace .exe extension with .bat, .com, .pif, or .scr like a screen below.

repcace file extension

Press Enter and then double-click on it to run.

Malwarebytes Anti-malware won`t run

Fix 2.1: Rename the main executable file.

Click Start, type in Search field %ProgramFiles% (if you using Windows 2000/XP, Click Start, Run, then type in Open field) as shown below.

Press Enter. It will open a contents of ProgramFiles folder.

program files malwarebytes folder

Next, open Malwarebytes Anti-Malware folder. Right-click on the mbam.exe file and select Rename option as a screen below.

rename mbam.exe

Type explorer.exe and press Enter. Double-click on it to run.
Note: several good names that you can use: explorer.exe, iexplore.exe, firefox.exe, userinit.exe, myapp.exe or use any random name

Fix 2.2: Boot your computer in the Safe mode.

  • Restart your computer.
  • After hearing your computer beep once during startup, but before the Windows icon appears, press F8.
  • Instead of Windows loading as normal, a menu should appear.
  • Select the first option, to run Windows in Safe Mode.

Run Malwarebytes Anti-malware or your security program.

Fix 2.3: Log in Windows using a new created user account.

  • Click Start -> Settings -> Control panel.
  • Click User Accounts and create a new account.
  • Reboot your computer and login Windows using a previously created user account.

Run Malwarebytes Anti-malware or your security program.

Fix 2.4: Run TDSSKiller.
Probably your computer is infected with TDSS trojan/rootkit. It may block various antivirus and antispyware programs from running.

Download TDSSKiller from here and unzip to your desktop.
Open tdsskiller folder and run TDSSKiller. Follow the prompts.

Fix 2.5: Use Inherit.exe to fix inappropriate permissions.
Use this fix, when you see a box that states “Windows cannot not access the specified device, path, or file. You may have inappropriate permissions to access the item”.

Download this file
Save it next to mbam.exe (this file is located in the Malwarebytes Anti-malware home folder). Once done, drag and drop mbam.exe into Inherit.exe. Click OK and attempt to run Malwarebytes Anti-malware once again.

Malwarebytes Anti-malware won`t update

Fix 3.1: Manually download and install Malwarebytes Anti-malware update.

  • Download Malwarebytes Anti-malware updates from here and save it to your desktop.
  • Double-click on mbam-rules.exe to install.

Fix 3.2: Copy the Malwarebytes Anti-malware definitions (rules.ref) from a clean computer.
You can update through MBAM’s interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes’ Anti-Malware (Windows XP and 2000) or C:\ProgramData\Malwarebytes\Malwarebytes’ Anti-Malware\rules.ref (Windows Vista and Windows 7) from that system to a usb stick or CD and then copy it to the infected machine.

Cannot use the Internet and download Malwarebytes Anti-malware or another security program

You will need access to another computer that has a connection.

From the computer download and save a setup package (installation file) to a flash, usb, jump drive or CD. Now transfer it to the infected machine, then install and run the program.
If you cannot transfer to or install on the infected machine, try running the setup package (installation file) directly from the flash drive or CD by double-clicking on the file so it will install on the hard drive.

  1. OMG thank you so much LOL
    this really helped me my malwarebytes wouldnt
    run cuz the Malware and it was getting so annoying

    Comment by Mason — June 15, 2009 #


    I can download the malwarebytes software and install it, but It will not run. I tried each fix you listed above, it still did not open and run.

    Researched a little bit more and found Combofix, great and all, but yep, downloaded, WON’T Install.

    I am almost ballheaded over this one. I have done scans with my AVG and I also used Windows Defender and Advanced System Care Pro for scans, they did no detect anything. But I am still have alot of instability on my pc. I keep getting those crazy *debug* error messages. I think I have a variant of the Windowsclick trojan because when I did a root kit scan, I got some suspicious files. I am trying to get them off my pc, but can’t get other spyware/malware removal programs to work. I am seriously going to shoot my computer with a shotgun. I have visited your site frequently in the last week and figured it was time I asked for help.

    This is the last file of the *16* rootkit items AVG *finally* produced.

  5. Personal Anitivirus was downloaded to my computer and now it will not go away at all. I am going to throw the dang computer if it does not go away. It wont let me do anything at all. I have tried the steps and still nothing. Is there anything else I can do. I am trying to download and i won’t let me at all. It shuts it off on me.

    Comment by megan — July 3, 2009 #

  6. Megan, try these Personal Antivirus removal instructions.

    Comment by Patrik — July 3, 2009 #


    I’ve been having the same problem. I tried renaming mbam.exe as myapp.exe, etc. Still MBAM did not start. I tried different names and what not. Then I remembered this annoying bug redirects me to all sots of webpages when I click on a link on the Internet but mostly to sites advertizing an antispyware program (stopzilla). I checked reviews on reliable sites and learned it’s malware, a rogue program, meaning that’s the program they want me to install in my computer. No way! So what did I do? I renamed the mbam.exe with the name of the malware(stopzilla.exe)!!! It worked!!! :) MBAM opened, I scaned, got rid of some spyware, updated, scanned again all files and got rid of more. (TAKE THIS STOPZILLA!!!)
    I did the same (rename the exe file) with Ad-Aware and Superantispyware and they got rid of more. Still I can’t open or update Spyware Doctor to get rid of more. I’ll keep trying and update you guys on this.

  13. Thanks very much for the help. I’ve had so many computers that malwarebyteswould not install on and all I had to do was change the program name. Thanks again!

    Comment by Chris Wakelin — July 30, 2009 #

  14. I am having a problem running the MBAM program. I can download it but then it asks me what program to use to run it, and I have no idea. Help!

    Comment by Chris — July 30, 2009 #

    Click Start, Run. Type command and press Enter. Type notepad and press Enter.
    Notepad opens. Copy all the text below into Notepad.

    Windows Registry Editor Version 5.00
    @="\"%1\" %*"

    Save this as fix.reg to your Desktop (remember to select Save as file type: All files in Notepad.)
    Double Click fix.reg and click YES for confirm.
    Reboot your computer.

    Comment by Patrik — July 30, 2009 #

  16. I seem to need help. I have tried all the steps, but my malware: “Windows Antivirus Pro” appears to have blocked every move for me. For your “Fixes” above:
    1. Despite renaming my Malwarebytes, Adaware and Spybot executables, they will not run.
    2. Folder Options no longer listed in My Computer, so I can’t unhide extensions.
    1. Will not run after name change.
    2. Blue screen of death when trying to boot in Safe Mode
    3. Cannot create new user accounts.

    I tried downloading malwarebytes on another pc, loaded setup exe to an sd card, even installed the program (using that setup exe) onto the same sd… then renamed all exe’s on the sd… then tried to launch the renamed exe’s (i named them all “bat” files) on the infected pc… they wouls still not launch.

    Have I stumped you? Reinstall XP with reformat?? Say it aint so!!

    Thx for any help! Glenn

    Comment by Glenn — July 30, 2009 #

  17. Glenn, please follow these steps so that I can have a look at the current condition of your machine.

  18. Thx Patrick, I am registering now and doing the Hijack steps… but as a side note, while I was awaiting your reply here, I clicked on your name and found the steps to remove Windows Antivirus Pro… I was able to complete the OTM step, but when trying to double click on the fix.reg notepad file on my desktop, I got an error saying my administrator would not allow changes to reg… but I am the admin and only user to my XP Pro pc… am I close? Thx!

    Comment by Glenn — July 30, 2009 #

  19. Update: i tried the Hijack steps, but failed… I installed HijackThis and ran a scan with log file… the scan happened, seemed to finish and present the log file… however, within 5 seconds, poof, the window disappeared before i could do anything… so i could not save the file or even copy/paste the text… i have now tried reinstalling and relaunching HijackThis, but it will not relaunch… :-(

    Comment by marnie — August 7, 2009 #

  26. My system was hijacked by and so none of the Antivirus programs including Malwarebytes would run.

    Did some research and came to this site. I followed the instructions to the letter and it worked!

    Thankyou, Thankyou and thankyou guys!

    Comment by Sheikh — August 10, 2009 #

  27. just some extra info i thought id share. i could install most the security programs but it seems like most of em need to be downloaded upon install now like a download manager… the last 2 jobs i did the malware blocked the domains for updating/downloading. so a quick fix is (in an updated copy of xp at least) run c:\windows\system32\mrt.exe if it wont run make a copy and rename it (just like steps above.) and do a full scan. it will find the dns changer and remove it. now you can install your security suite and spybot. (i find that malwarebytes wont run till after i do spybot) just my 2 cents. hope it helps.

    Comment by Craig — August 10, 2009 #

  28. I am unable to install the program. Every attempt freezes during the *Finishing Installation* portion of the install process. I have tried to install the file from safemode, as well as changed both the filename and the extension with no luck. Is there any other way I can install the file?

    thank you so much for your help.

  55. I was having major headahces getting ANY security software to run. Been trying to fix my PC for the last 16 hours straight and I was getting nowhere. Most software would install but couldn’t do anything after that. I followed the instructions further up regarding changing the filename of mbam.exe to stopzilla.exe. What do you know, the bloody thing ran first time – thank you for that post – YOU ARE A LIFESAVER!!

    Comment by Mick Barber — December 7, 2009 #

  56. Nice one, renamed setup file and it installed.

    Once installed it would not run.

    I then renamed execution file and it ran perfect.


    Comment by the dude — December 9, 2009 #

  57. My Malwarebytes Anti-malware were installed after I downloaded and renamed it to something random. But the mbam.exe won’t run after installation no matter what I rename it to. So this is what I did:

    I uploaded mbam.exe as an email attachment and sent it to myself. I downloaded that same attachment and renamed to some random name and saved to the original folder that mbam.exe was in. I ran this new file that I just downloaded and it works :)

  60. I couldn’t get it to run either – no error message, nothing. It wouldn’t uninstall either – it would flash up the ‘are you sure’ message really quickly and then just disappear.

    So I had a look in the malwarebytes directory of one of my working computers, and found that the file ‘ssubtmr6.dll’ was 2K different in file size. I copied that file from the working computer to the stricken one and guess what? MBAM is running! Obviously this is no help whatsoever to someone without an extra computer… sorry about that!

I just got this 2 weeks ago, have only done minimal things as of yet and had over 60 infections. Thank you thank you thank you.

    Comment by Lori Kindler — January 10, 2010 #

  68. I have “Antivirus live” worm. The first thing i did was disconect from my internet conection, now when i try to conect to a network it does nothing (does not pick any conections up and conect button is fazed out). When i go onto internet explorer the “TOOLS” button is not there so i can’t change proxy settings.
    I manually deleted some HKEYS which has stopped all the pop ups.
    I have tryed to run Malwarebytes but keep getting a message saying- “run-time error 53, file not found: advpack” whilst downloading from disk.
    I’ve tryed changing the name of the file.
    I tryed to run ‘ISPFIX’ ‘AVENGER’ TDSKILLER but say program not found.
    I’m doing everything in safe mode.
    Done Hijackthis and deleted the HKEYS recomended no other keys look suspicious to me, but as have no conection can’t copy and paste. Don’t want to usb it to my good computer incase it becomes infected.
    went ahead and done combofix it said can’t complete deleting files as need administration rights.
    can’t create a new user in control pannel.
    I done ‘RKILL’ which gave me back taskmanager and folder options however can’t stop any processes in TM and click folder options does nothing.
    Just let it run in normal mode and the wallpaper has changed to a random photo i’ve never seen before????
    No programs work that were installed before virus.
    Was using Avast at the time which alerted me to the virus but aparently did nothing! I just want to re-install windows but need to get some important files off first. These files are under hidden properties and as i can’t use my folder options i can’t get to them. Someone please help is there away off getting to my files without spreading this virus?

    Comment by Kev — January 13, 2010 #

  69. Kev, you can attach the infected drive to another PC, then scan it using an antivirus. Once finished, move all important files and re-install Windows.

  72. I’ve downloaded malwarebytes but will not install. Says version is corrupt. Tried the downloaded version and also tried it from a CD copied from a good PC. Both say they are corrupt versions even though I know they are not. Tried renaming both of them (file names and changing from .exe) and nothing.

    Comment by Roger — January 20, 2010 #

  73. I have done all of these things above, Have the Anti-virus Live worm as well.

    I was able to get internet access by going into internet explorer -> Tools-> Internet Options -> Connections -> LAN setting -> and unchecked used proxy settings.

    Now when I try to download the Malwarebytes software it gives me an Error Creating Registry key upon download. Then it doesn’t allow we me click on a hard-drive to scan.

    Any advice?

    Comment by Jennifer — January 21, 2010 #

  75. Hey! I had to use a proxy website to get here since my malware is blocking this website but None of the suggestions worked for me. I read a comment about how someone changed theirs to stopzilla.exe so I just searched malwarebyes anti-malware and thhen let them redirect me. Mine kept showing search and destroy pro so I just changed it to searchanddestroy.exe and now it finally opened! Thanks for that great suggestion.

    Comment by E — January 21, 2010 #


    I had the stupid malware that tries to get me to install a fake Malware Defense program.

    At first I downloaded Malwarbytes on my infected computer, by changing the exe file to mdefense.exe, which is the name of the fake anti virus program that got installed on my computer. It worked but I couldn’t run it.
    I downloaded it from another uninfected machine, then renamed the mbam.exe to mdefense.exe. I moved all the malwarbytes files from the malwarbytes folder of the good computer on to my infected computer, BUT put the files in the Malware Defense folder. Which is the folder the trojan installed for the fake anti virus software. And malwarbytes opened and scanned!

  77. just wanted to say thank you. your writeup saved me my job today. all i did was dl the random mbam name. and move it to my malwarebytes folder. and mbam came right up. updated fine. and found 22 processes that needed to be cleaned. restarted and scanned in safe mode to be sure. 0 items found. then restarted in full windows. and quick scanned again. looks like all is well. thanks again.

  86. Xvaier is a LEGEND. This worked for me.

    Used Fix.reg code (had to manually import by using RUN>regedit. Rebooted PC (pop ups then stopped). Downloaded mbam-exe using uninefected PC, renamed file and installed onto infected PC.
    mbam would not run after install so I renamed file stopzilla.exe and hey presto, its running.

  88. Okay everyone who is having trouble getting Malwarebytes to run even after renaming MBAM.exe to
    something else like stopzilla.exe. I first renamed the MBAM.exe file and then it installed. However, no matter what I tried, it wouldn’t run. Rereading the posts above, I came across the one by”the dude” who said he renamed the exe file in the Malwarebytes program folder. Tried it and voila = opened and ran perfectly.

This has happened to me before and I had to uninstall it and install it again. This time I can’t do that because it wont let me get online. I was wondering if someone could explain to me how to download it from anothe computer onto a disk and then load it on my computer.

    Comment by SARAH — March 6, 2010 #

  102. how to download it from anothe computer onto a disk and then load it on my computer.

    Its simple. Download Malwarebytes installer (mabm-setup.exe) to another PC, them copy this file to your flash disk or using any burn software to cd disk. Insert the disk to infected pc and run it.

    Comment by Geoff — March 17, 2010 #

  117. Use Sophos ( to remove the root kit virus. reboot, then download CureIT ( make sure you update it. Sure IT will clean up the areas where you cant run programs such as malwarebytes. Once you run these programs, malwarebytes should be able to work and run it to clean up the rest of the malware. This is a rootkit problem thats very pesky. and check your task manager for any programs that look suspicious, one way i found it was i was using firefox and iexplore.exe was running in the background.

  121. Another simpler way I found recently, cuz I’ve had this issue forever with not being able to update Malwarebytes – was to download Malwarebytes 1.45 beta. Just run the new Flash Memory scan. It found like 3 traces, after a required reboot, I could update Malwarebytes again. :). After updating, you should run the flash memory scan ‘n a full scan again. I found 1 more trace in flash memory after update, and a dozen more in full scan.

    Comment by XtraTrstrL — March 26, 2010 #

  122. AVG Grifsoft reported several Trojans on about 3/17/2010, could not remove all of them. Malwarebytes Antimalware executable mbam.exe was missing. AVG did not report anything more, popups stopped, but computer slow, expecially when booting WinXP.
    Tried to reinstall Malwarebytes Antimalware on 3/27/2010, renaming the downloaded installation executable, in renamed folders. Watched the installation on Windows Explorer: mbam.exe was always wiped out as soon as installed, before it could start.
    Downloaded mbam.exe with random name, started quick scan. It found 28 trojans/problems: Security.Hijack 1x, Disabled Security center 1x Wundo 1x, Wundo.H 25x.
    Updated definitions and started quick scan again. It found 4 trojans: Security.Hijack 3x, Trojan Dropper 1x.
    I have to reboot now. I will run quick scan until everything is clear and then full scan until everything is clear.

    Thank you, Vladimir

  123. Hi, I did step1 with notepad, no problem.
    In step2 when click on “Download MalwareBytes Anti-malware (MBAM)”, it send you to the top of page to download “spyware doctor”. Instead of icon
    mbam-setup.exe, I have icon “spyware doctor” (pctsGui.exe) and after click on it, opens totaly different window “spyware doctor with antyvirus”.
    So, how to get “mbam-setup.exe” to open Majwarebites window ???

  129. Ok I’ve googled for hours, followed a bunch of faqs and instructions and I’m to the point where I’m feeling hysterical enough to pull out my hair. Not one solution on any forum or website is working for me. My initial problem is trying to remove antivirus suite. I’ve downloaded HijackThis, MBAM, TDSSKiller, Avira Antivirus and the inherit exe to go with MBAM. I’ve tried to run every program and been stopped, I changed the filenames and have run all the programs in safe mode. MBAM always comes up with a runtime error when I try to run it, avira won’t install and always closes itself, and TDSSKiller runs, finds nothing then is closed with a prompt. I’m desperate for a solution.

  131. I’ve had the pop-ups going for 2 days, but i had this problem before and i don’t want it to get worse. I tried ccleaner but, it didn’t seem to work. I’m open for any suggestions. I’ve tried all the ways to download this. But with the spy-ware “XP Defender” (it’s the new name it’s chosen for the past hour) won’t let me download any .exe files. I keep getting the ““Windows cannot not access the specified device, path, or file. You may have inappropriate permissions to access the item” error”. And on that step, where is the the “malwarebytes Anti-malware home folder”, i can’t seem to find it.

  150. renaming the old and new malwarebytes .exe
    to .com allowed malwarebytes scanner to run for me. it took some practice with mouse speed and hand coordination, (with task manager open
    to the processes tab click “image name” tab
    to alphabetize the programs that are running). seems you only have a second after starting your good scan program to mouse over to Windows Task Manager to click on the offending virus/spyware program when it starts and “end task” . if your quick your .com scam program will start. i’m now scanning, after two weeks of messing with msconfig and regedit. thanks to all of you who helped me understand some of this stuff!!!!!
    I hope this Malwarebytes scan kills the source. ALSO four guys are being brought up on fraud charges for creating this crappy scam and ripping off pc illiterates for millions.
    they probably use the money for “good” lawyers.
    I hope someone out there can enlighten a news
    station do follow that legal story. ALSO, executing iexplorer seems to instigate the malware,
    so keep an eye on task manager for a coordinated
    malware program startup that you can kill.

    Comment by patrick — April 11, 2010 #

  151. ALSO , my problem has been “XP Antimalware”
    spelling correction on previous post:
    “if your quick your .com SCAN program will start.”
    by instigating various .exe programs you can witness the bad malware program starting up at the same time in task manager.

  157. OK, wasted day on this mess. I have the xp smart security mess. I tried one fix I found on this site, which had me create a fix.exe file, then download malwarebytes, install and run it. I was able to create the file, but it wouldn’t run because it said registry updated were disabled. I thought I could go ahead and still try to install malwarebytes. It allowed me to install it, but after two scans…each taking over an hour, when it said it was complete, I selected ok, and then it simply closed. I was never given the option to fix or remove the issues. So, I did some more searching and found the other fix, which had me create the fix.ini file, select install and then reboot. I also found what appears to be a more up to date version of malwarebytes (this one has 1.45 in the file name). The install of the fix.ini went well, the reboot ok, I was able to install malwarebytes and it is currently scanning…but concerned it is still going to close. Suggestions?

    Comment by Anthony — April 16, 2010 #

  161. Thanks…I had the XP antimalware 2010 popup..nothing worked, luckily I found this through going through the aol software..and surfed..this is what worked for me…

    Fix 2: Change Malwarebytes Anti-malware or another security program installation file extension.
    Turn on “show file extensions for known file types” by doing:

    Double-click on the My Computer icon.
    Select the Tools menu and click Folder Options.
    After the new window appears select the View tab.
    Put a checkmark in the checkbox labeled Display the contents of system folders.
    Remove the checkmark from the checkbox labeled Hide file extensions for known file types.
    Press the Apply button and then the OK button.
    Now your computer is configured to show file extensions for known file types.
    Right-click on an installation file (the mbam-setup.exe file for Malwarebytes Anti-malware) and change the .exe extension to .bat, .com, .pif, or .scr. Press Enter and then double-click on it to run.

    I hope this helps everyone to defeat these monsters…

    Thanks for the help

  169. Hello. I did the .inf fix and then tried to fix the .exe but I can’t get the registry editor to open. I keep getting an error box that says, “C:\Windows\system32\clb.dll is ither not designed to run on Windows or it contains an error…” I am so stuck.

  171. You have to go into your program files and change the exe for ‘Malwarebytes’ Anti-Malware’ to a different name

    *The reasoning behind this is that the virus itself will actively block ‘Malwarebytes’ Anti-Malware’ so it won’t be removed, and if you change the name of the exe program to something else, the virus won’t be able to block it. I changed my file name to ‘Steam’ and it worked fine.

    **Props to this site for this easy solution, I wouldn’t have thought of it myself

    Comment by Malwarebytes User — April 28, 2010 #

  172. It should be noted that if cannot get Malwarebytes to install, download the file, rename the setup.exe and run it. You are given two opportunities to change the name of the folder and something else which I can’t remember but it says “Malwarebytes Anti-Malware”. RENAME ALL OF THESE instead of just the .exe. file and then everything should work just me.

    It seems in my case, Digital Protection won’t let anything run that is associated with Malwarebytes or within a folder that is named that.

  173. I have recovered my computer system from personal security, thanks to malware, although I still have the personal security icon in my toolbar and in windows setting / control panel. How do fix this?

    Comment by Norbert — May 12, 2010 #

  174. Norbert, probably the rogue uses an icon of legitimate Windows components. If you think that your PC is still infected, then open a new topic in our Spyware removal forum. I will check your PC.

  175. I’ve tried everything listed here several times and Malwarebytes won’t run. I’ve tried everything I can think of to no avail.

    This doesn’t bode well for the internet. I’ve got users who don’t have admin rights getting infected just by browsing the web. You used to be able to defeat these with safe mode and the proper removal tool. Not anymore.

    Comment by Tim — May 13, 2010 #

  176. Follow up to my previous post.

    I’ve discovered that some rogue anti-viruses disable Malwarebytes by preventing it from loading it’s definition database.

    Uninstall Malwarebytes and run mbam-clean.exe from the Malwarebytes website. Reinstall Malwarebytes, let it load and update, and scan. This worked for me.

    Comment by Tim — May 17, 2010 #

  177. I don’t know how many Vista users are having this problem, but I found an easy solution: if you’re having trouble running .exe files, simply run the file as the Administrator (left click it) and it should run fine. I just did that and ran Maleware and it deleted everything fine.

    Comment by Bryan — June 4, 2010 #

  178. plz i need help!! everytime i use full computer scan/quick scan on the malwarebytes Anti-malware a error message pops up and tells me to report it to malwarebytes support team, the message is ” MBAM_ERROR_LOAD_QUARANTINE(0,6), everytime after i click ok it shows a object infected. after the scan is done it says you have successfully delet it. but when i re-scan it, it shows the exact same trogen.plz help!!

    Followed these instructions.

    Saved a day of headaches.

Then ran it on the infected computer in Safe Mode with Networking. Ran “scan whole computer”. It found all of the bad guys and fixed them. Infected computer is back to normal. Hope it works for everyone else with this rotten apple.

  227. Please Help!
    My laptop has been horribly infected by the Internet Antivirus 2011 virus. I can no longer access the internet from the laptop. After reading this site these are the steps I have taken but have been unsuccessful in running the Malware software.

    1. I saved the install program to an external flashdrive. I tried running it but ran into issues as the Malware program was trying to access the internet to download files and I came onto a page asking for the ip address. So I moved on to step 2.
    2. I actually installed the Malware software on the flashdrive. But when I tried running it when attached to the laptop. I got 2 runtime errors. The first one the screen heading \vbAcceerator S GridII Control\ Runtime 0. And the ohter \Malwarebyte Antimalware runtime 440 Automation Error\

    Oh and I also tried renaming the exe before running it.

    Please help. Any suggestions. Would be so appreciated. My 2 1/2 year old son misses the laptop too. He’s already tried calling the \bad man\ to yell at him for breaking his computer. Cute but besides making me laugh it too did not solve the problem.

    Any further suggestions would be very greatly appreciated.

  229. Hi I have this virus/malware. I had a run in with its first incarnation in Virus Scan 2010 and was able to get rid of it with Malwarebytes in November. This time I am having significantly more difficulty. I think I made the mistake of not updating Malwarebytes before running it. It found one unwanted program and deleted it. However when my computer rebooted the malware was still there and Malwarebytes wont run. I rebooted in safe mode but malwarebytes still would not run. I also no have no access to the internet on that computer. Antivir which is the antivirus software I have would run and detected 5 virus/malware programs and quarentined them however after full reboot the Virus/Malware is still there and preventing malwarebytes from running and preventing access to the internet. Antivir is currently running another scan. If that fails then what?

  257. I had the Antivirus 2011 and currently using vista. I downloaded this antivirus called STOPzilla. It found the antivirus but its saying I have to buy the full product to remove it. I ignored it but the anitvirus is gone(I think). Now when ever I try to open .exe file a *open with* window shows up. I don’t know what to do here so I closed it. I can run firefox and other stuff by right clicking and pressing start, thats how I was able to download malwarbytes but It said I still have to purchase to remove the infected files. I have this online game I want to play but when I try to right click start, it won’t open. Normal clicking any .exe file will just bring up the *open with* window. Please help me and I don’t want to purchase anything to fix a 2011 anitvirus scam. I am using Vista

What worked for me was creating a new user account, restarting, then logging in under the new user. This allowed me to be able to get online, download malwarebytes fresh and do a full scan! Thanks you so much for that tip because I had been trying for a full day to get rid of this mess!

  261. Hi,

    How does one access or find all of ones programs again after the Windows repair virus has done its work?

    Malewarebytes, plus a few other antivirus programmes have done their work – in that they have managed to remove a number of virusz off my laptop, but now I cannot find Word etc.?

  262. I have malware calling itself XP internet security 2012 firewall alert on my laptop. I have downloaded malwarebytes antimalware on my external hardrive from another computer, but it won’t run on my laptop. I have changed the name to all things suggested above. I have run in safe mode of all variations. I have tried the tddskiller which won’t work either. The malware has complete control of my laptop and won’t even let me open a new user account as it says windows is a virus. I’m out of ideas, any help gratefully received! Thank you :)

  263. I have tried renaming Malwarebytes etc.
    Still no success.
    I can’t even rebbot into safe mode via F8 key.
    Personal Shield Pro blocks me from entering all sorts of virus cleaner/protectors.
    Is purchasing this package the only solution?
    Please help! don’t want to lose files.

  264. Hi,

    My grandson by mistake down loaded “XP Antivirus 2012″ while using face book resulting in the obvious consequences,despite my best efforts I was unable to remove the Malware because my security programs would not run. Then I decided to try one more time, I ran system restore in safe mode and restored it to its last good setting and “A Presto “everything is up and running again. My grandson runs a E machine notebook using XP OS.To finish I updated his security system and run the necessary scans,Malwarebytes found a small problem and it ended up the vault.

    I hope you find this useful.

  266. Hey guys, I’ve tried all of the above suggestions going from re-naming it to running it in safe mode.

    I can install MBAM but when the window comes up and i can click scan, but as soon as i do this the window will do a few seconds of the scan the shut down. When i try to re-open any anti virus software i keep getting the same error message: Windows cannot find the specified file name etc or you may not have sufficient authorization to do so.

    If anyone has any tips or help please message me :)

  267. Lauren, you have tried to run TDSSKiller before Malwarebytes ?

  268. i am running into the same exact problem. i followed everyone of the steps above, but my computer is still sick… what do i do next?

  269. So, I had the data recovery virus and walked through the steps above…had to play with file names a bit and I can tell you that renaming the exe files with something random worked like a dreamed! Was able to successfully run Malawarebytes and TDSSkiller – result were pretty consistent with the instructions above…however, now that the virus appears to be gone, my desktop, favorites, program files, etc. keep defaulting back to some generic configuration. I tried to unhide all my user data, as well as all user data but I think I’m missing something simple and making this harder than it needs to be…any suggestions on how to get my settings back to where they used to be? I have windows xp and the entire family uses one login (which is still sitting in the background intact but I can’t get it to load). Thanks so much for your help over the years. You’ve saved me lots of tears and your assistance has been better than anything I could get from our local IT guys.

  270. Thank you very much for this ! ! !

    TDSS Killer managed to remove the trojans that was preventing malwarebytes from updating.
    Inhibit then allowed it to run properly as it had been crashing half way through the scan.

    Just a note for everyone, do not use Zonealarm as it is very system heavy especially on laptops. It also failed to prevent the trojans and malware that I had caught from simply viewing a website.

    I’m switching to Avast now, hopefully with better results.

    Again, thank you for your time and effort !

  273. Windows Crucial Scanner has infected my laptop, which is awesome. I’ve been following all your steps in How To Remove windows crucial scanner, and so far it has all worked except this: I’m trying to download Malwarebyte’s Anti-Malware and it’s not downloading. The screen says, “Your download will begin in a moment…” and I’m not sure how long their definition of a moment is but it’s been like 15 minutes. When I visit the Download Help Center, none of the tips seem to apply to my situation. I tried the Publisher Profile thing, and it just led me to the same place. Helppp

  279. Thank God I read through all of these questions and answers before I did anything! I just went ahead and changed the name to winiguard.exe and it asked if I wanted to update. I clicked yes, and then it updated fine, so I then clicked on full scan and as I write this (on my desktop), my laptop (Vista) has detected 18 objects so far. Whew, it’s been a long and hurting 3 days (with a broken clavical bone!) Patrick, you are a saint! I didn’t even go through the steps above and just went by what worked for others. Thank you so much for your time invested! Let’s just hope this gets through ALL of my Drive and doesn’t quit on me! If it does…tomorrow is another day. I just can’t deal with this any longer tonight! Thanks again Patrick, and all of those who went through the trial and errors!

  281. I simply downloaded Malwarebytes on a laptop, transferred it to the desktop infected with sodding live security platinum then right clicked / copy / paste and ran the copy of Malwarebytes, installed and ran a full scan

  282. Great information. Lucky me I found your

  283. WOW!!!!!!!!!!!!!!!!!!! Hours and days and weeks long of the annoying issue…couldn’t run antimalware from external hdd, couldn’t download anything, but the idea of changing mbam setup to stopzilla.exe worked!!!!! THNX XAVIER….ONLY THING NEEDED WAS TO DOWNLOAD SETUP TO FOREIGN DEVICE and plug, rename, and run as normal.

  284. if malwarebytes wont run and chameleon cant be started then try the following
    1 in safe mode change the name of the malwarebytes directory in the program files
    2 remove the desktop link in the program list on the start menu
    3 download a new copy of malwarebytes and open the file in the download directory as an administrator ( dont run the link directly from the download )
    4 when it asks you where to install the program install it to a different directory in program files
    5 when it asks if you want a startup link say no
    reboot and the program will run

    whatever process was trying to stop malwarebytes from working cannot now access the program because there is no path available

    I hope this might be of some help it worked for me
