  49. Thank you so much! that was amazing

    Comment by Jam — April 21, 2009 #

  50. This is so insanely simple, the guy is a genius!

    In the worst case, one of these flash drive trojans can prevent access to any drive on your machine. Click on the drive and nothing happens, or a warning comes up that the drive is not accessible or some weird piece of software (like notepad) runs.

    The way a flash drive spreads a virus or trojan actively (as opposed to just copying infected files which the method above does not stop), is by the autorun.inf file being set to run the trojan on the flash. That then infects the whole machine and any drive connected also gets infected. In the mean time the trojan can go off and download hundreds of other payloads. Good luck to clean that lot.

    One way of stopping it is to turn off autorun properly (not easy – most solutions don’t work in special cases) or do what this does.

    Just delete the autorun.inf and add a folder with the same name that is locked. So the autorun file can never be written. Then do that to the other drives on your machine and you are 100% protected against any other flash drive.

    Why didn’t I think of that?? Duh!

    Comment by Maynard — April 22, 2009 #

  51. Maynard, yes bot variants are good. But autorun.inf folder is more simple and can to protect your Flash drives.

    Comment by nazar ali — April 27, 2009 #

  53. I have downloaded this several times – to desktop and also downloads. Both open to a “do you trust this program” screen, I click Allow, and nothing else happens. I have Vista with a virus coming up as ‘Worm/Autoit.yry’ that had been solved beforehand(by someone else). I just used my USB drive (previously infected before fixing) and now it has same-named apps dated 19.10.08 in all the folders. Curious at first, I clicked on one, but nothing happened and I can’t delete it now. I can’t open task manager. What do you suggest?

    Comment by L — May 4, 2009 #

  54. You have disabled your antivirus ?
    Also you can ask help at our forum.

    Comment by Patrik — May 4, 2009 #

  55. mmmm…
    i use avira or kaspersky for deleted that viruses..

    but not always can detect the new trojans..

    for that, i use KiyoScanner v0.3 =)

    can desinfect all virus usb:


    and 2000 more types of usb malware
    and can repair regedit =)

    I had been banging my head trying to get rid of malware that got in my flash from a quick visit to a net-cafe (!$#%*.
    I also suggets everyone use a very good anti-malware stand alone. After Flash Disinfector I ran Prevx 3.0 which found 3 more that the original Flash infection had blocked. Prevx now runs constantly – good prog!
    Thanx again.

  131. Chris, it should work.

    Comment by Patrik — July 23, 2010 #

  132. Help needed urgently.

    I have a Café Internet, and although I reinstalled all my PCs a month ago, protected by Avast, Panda USB Vaccine (PC vaccinated), plus Deep Freeze, etc. from the beginning; all of them are already infected by bunch of bugs. I keep getting rid of them with Malwarebytes and Spybot, but they come back on reboot. How did they get infected anyway? I wonder if a user intentionally installed those bugs.

    How can I get rid of them and protect my computers for good silently, that is, by applying the vaccine automatically, without having to execute Flash Disinfector before inserting the Flash Memory. If someone wants to infect the PCs, won’t apply the vaccine manually. I am convinced that my computer get infected by all the USB flash drives inserted daily.

    By the way, does Flash Disinfector clean an infected computer and how? Or i have to run other cleaners?

    I am confused with the concept Flash Drive. I don’t know when you are talking about a Flash Memory stick or a USB port/drive. Does Flash Desinfector clean the Flash memory stick or the USB port, or both?

    So, if I installed Flash Disinfector it will clean all the bugs on my PC?

    Can someone explain the difference?

    Thanks for your timely reply in advance.

    Comment by Fiantella — July 30, 2010 #

  133. Fiantella, you can use Flash Disinfector to protect a computer drives. Also a good idea – to disable autorun autorun feature to prevent malware from spreading.

I’m running windows 7 64 bit and while I think it would work on the 32 but version of the system, I’m getting the sense it’s incompatible with the 64 bit system. I’m in the middle of trying to disinfect my brother’s computer and need to use this to check if the Flash-drive I’ve been using to go between my clean pc and his infected one is still clean. (his pc is VERY badly infected :/)

  143. “Flash Disinfector” good utility for removing autorun virus. it is not virus,spyware, an malware.
    do you know many antivirus software can not delete autorun can be dangourus for your mobile, and computer. so you can use “Flash Disinfector” utility for removal of autorun.inf virus.

  149. Hi!
    I can’t download flash disinfector! Can’t do it through the link you posted nor through any other link I found in the Google. I’m using Google Chrome: does it have anything to do with this? Should I use the Internet explorer?
    Thanks in advance

  155. I like Flash Disinfector. Elegantly simple utility/function. However, having autorun.inf folder prevents windows from displaying drive volume label. Any way around that?
