Please recommend one freeware to prevent USB flash disk from virus

    Sometimes, I plug USB flash disk into various unknown computers. And I don't
    know if these computers are free from virus or not. What can I do?

    Put the flash disk in a rubber, and DON'T KISS!

    I assume you are worried about bringing malware back to your computer from
    the infected flash drive. Boot your computer with a Knoppix disk and reformat
    the flash drive FAT 32 before you allow the machine to boot into Windows.

    This will help:

    a.. Please download Flash_Disinfector.exe by sUBs and save it to your
    desktop:
    http://download.bleepingcomputer.com//sUBs/Flash_Disinfector.exe

    b.. Double-click Flash_Disinfector.exe to run it and follow any
    prompts that may appear.

    Note: Some security programs will flag Flash_Disinfector as being some
    sort of malware, you can safely ignore these warnings

    c.. The utility may ask you to insert your flash drive and/or other
    removable drives including your mobile phone. Please do so and allow the
    utility to clean up those drives as well.

    d.. Wait until it has finished scanning and then exit the program.

    e.. Reboot your computer when done.

    Note: Flash_Disinfector will create a hidden folder named autorun.inf in
    each partition and every USB drive plugged in when you ran it. Don't
    delete this folder. It will help protect your drives from future
    infection.

    Is it your recommendation to download an undocumented executable from
    some Internet site to your computer, run it, ignore any warnings by
    your other protection mechanisms that the software may be malicious,
    plug in all your USB devices - including your mobile phone. and let
    this software do whatever it does to them and then be content that you
    are protected from "future infection" via the addition of some
    autorun.inf folder on your devices?

    Considering your frequent posts about how to detect and remove malware
    using tools like MBAM and S*perAntiSpyware, I would have thought you to
    be familiar with bleepingcomputer.com malware removal forums and
    instructional pages for removing malware variants, as well as the many
    tools they host and use there, written by sUBs...such as
    FlashDisinfector, and ComboFix (which is an advanced tool to be used
    under the direction of an experienced handler).

    It's not an undocumented executable if you are familiar with malware
    removal, and work in forums that use such tools regularly for malware
    removal. I'm sorry you are not familiar with it...feel free not to use
    it. The warning that it may be detected by some security programs as
    malware is true for many many anti-malware tools. I'm surprised you do
    not know this. I keep a folder of such tools separate so I can set my
    AV to ignore it rather than have repeated warnings. Surely you know an
    antivirus program will often raise an infection warning if another
    antivirus program is on the system and it detects the virus definitions
    of the other as malware.

    No one (except you) said to "feel content you are protected from future
    infection"...it states quite clearly "It will HELP protect your drives
    from future infection." Having an updated antivirus running will HELP
    protect you from future infections also....but it doesn't guarantee you
    are protected and should feel content. Using tools such as
    SpywareBlaster, SpyBot S&D, MBAM resident protection, and so forth, will
    HELP protect you but that does not suggest you can be content either.
    Following your argument, we should forego having an antivirus or any of
    these tools, because it can't protect against all future infection
    either....it "only" HELPS.

    Well, if MBAM and SAS are not your cup of tea, maybe you can download
    that Flash_Disinfector and have it scanned by a few online scanning
    sites like:

    www.virustotal.com (40+ reputable/popular scanning engines)
    www.jotti.com

    Taking a look at all the scanning positive results, threats and
    possible threats and perhaps help us understand exactly what
    Flash_Disinfector is, what it is supposed to do, what does it prevent
    and how it does it (this may be proprietary though). Do I just run it
    once a day/week/month? Right now it looks like a terribly infected
    file - as a matter of fact, I don't recall one in recent memory with a
    worse report.

    Are these the possible threats you are talking about and is it okay to
    ignore the results? Does that mean these scanning softwares are wrong
    or is this just an insulated icodent?

    I would usually consider it bad judgement to just download some
    executable and just run it without checking it out first and I am
    happy to try it to learn if it is useful tool for me to use now or
    ever.

    I did go ahead and run it when several portable devices installed and
    did not see anything but an hourglass for a few seconds. Is that
    normal? Should something happen to my autorun.inf files - some drives
    have one and some don't. Does it somehow toggle autoplay? That
    didn't work either. Or should it create a new folder? Nothing is
    obvious, but my expectations may exceed reality.

    Maybe the link is not working? What are the results you get?

    I didn't say anything about MBAM or SAS not being "my cup of tea"...I
    use MBAM as a removal or detection tool regularly. You seem intent on
    putting your words in my mouth, and re-writing what I posted to suit
    your argument.

    It was already explained that it might, like many other tools to fight
    malware, trigger alerts by virus scanners.

    It was already explained that it would create a hidden folder named
    autorun.inf in each partition and every USB drive plugged in when you
    ran it. That is what I see on every system on which I have used it.

    If you don't want to use it, don't use it. It is a tool I and many
    others in the malware removal community use and recommend, including the
    forums at MBAM. The tool has been hosted for quite some time at
    http://www.bleepingcomputer.com/ where sUBs is a valued member,
    respected by everyone in the field.

    If you feel he is not trustworthy, contact Miekiemoes, who is a member
    of the Malware Response Team at Bleeping Computer and also at the MBAM
    forums, where she is an Administrator, and also Assistant Director of
    Research at Malwarebytes....she will, I'm sure, vouch for the safety of
    Flash Disinfector by sUBs, and for sUBs. Google: Miekiemoes and you
    should have no trouble finding a way to contact her.

    If you want to discuss their hosting of the file or its usage, I suggest
    you contact Bleeping Computer and they may put you in touch with sUBs.
    Again, I am very surprised you have no familiarity with
    bleepingcomputer.com.....I suggest you become a member there or at the
    MBAM forums, and at least spend some time reading there if nothing else.
