How to remove System Fix virus

System Fix a fake computer optimization software that detects numerous false problems and displays various critical errors alerts on the computer. The rogue program from the same family of malware as Data Restore, Data Recovery, Master Utilities, PC Repair, System Repair, Windows XP Repair, etc. It is promoted and installed itself on your computer without your permission and knowledge through the use of trojans or other malicious software. Moreover, the scammers may also distribute System Fix on Twitter, My Space, Facebook, and other social networks.

While System Fix is running, it will block legitimate Windows applcations on your computer and won’t let you download anything from the Internet. Moreover, it will display various fake critical errors alerts that the computer’s hard drive is corrupt in order to frighten you into purchasing this useless application.

It is recommended that you restart the system.

  2. Wow, thank you so much for the detailed guide, this helped me so much!!

    I was running Norman Antivirus and it detected a trojan, moved it to quarantine, but apparently that wasn’t enough, in the meantime my computer started acting crazy and was getting many fake popups telling me my hard drive, memory, etc were failing and all my files disappeared which freaked me out!

    I came across this post when I was Googling System Fix and following the guide seems to have fixed all the issues. I’ve now deleted Norman and am running Kaspersky which I’ve been successfully running on other computers, never going back to Norman again, this is the second infection it has allowed to occur!!

  4. Thank you very much for this very clear solution to a very irritating and worrying problem.

  5. Thanks very much! This is the only guide I found that actually told me how to fix the damn thing w/o having to install whatever AV they were trying to sell. Spyware Docter identified it, but failed to remove it (glad I didn’t pay for the reg code ;-P ).

    The only addendum I would make would be to run a system restore once you get the virus all removed. TDSSKiller wouldn’t run for me, but ComboFix did the final cleanup. After I reverted to a restore point from before the infection my machine was fully back to normal.

  6. removed the virus – thanks – but all my program and data files are still “hidden” – how can I can make them reappear?! Thanks.

    Comment by steve — November 26, 2011 #

  7. Thanks. This stopped the annoying fake warnings, but my programs and documents are still invisible. I could not for some reason get TDSSkiller to work. And when I ran combofix, it became ran as some other name, purported to find over 1,000 issues. It said it was “free,” but when I tried to use it to remove all issues, it asked for money to “register.” I declined. Any advice is greatly appreciated.

  8. Many, many thanks. I followed the same procedure but used SuperAntiSpyware instead of MalwareBytes. I am a tech and have a license for SAS, thats why the change. The key was stopping System Fix from auto starting in step 5. In my case TSSDKiller did not find anything.

    I had to do one extra step – right click Start and set Control Panel, Computer, etc. to display as menu. Worked perfectly. Thanks again.

  9. Thanks for this. Changing the file names and using Malware stopped the fake alerts. However my programs and files are still invisible and the computer is super super slow. Also y searches are redirected to ads posing and legit websites. I was unable to get TSKiller to run. I tried combofix as suggested, but it downloaded as something called by a different name, one I cannot recall. It claimed to be free, located over 1,000 issues, then wanted $ for “registration” in order to remove them. I opted not to pay and deleted the now suspect program. If anyone can give further guidance, I’d appreciate it. thanks

  14. Omg thx soooo much!

    Comment by jae breeze — December 7, 2011 #

  15. Thanks for your help, the one additional step I had to do before deleting the files was to copy the files in the Temp folders to another location to get all my shortcuts back:

    %Temp%\smtmp – C:\Documents and Settings\All Users\Start Menu

    %Temp%\smtmp – C:\Documents and Settings\Username\Application Data\Microsoft\Internet Explorer\Quick Launch

    %Temp%\smtmp – C:\Documents and Settings\All Users\Desktop
