    It might be detected as Trojan.Moo or any other variant of the JPEG
    exploit. As I said, it attempts to exploit the system to see if it's
    vulnerable, using an "infected" JPG. The file I provided is simply a
    SFX with a batch file and the "infecte" JPG (named exploit.bak). No
    attempt has been made at all to mask what's inside.

    I figured those that would want to use it would either not worry about
    the virus warnings, or not get them at all and REALLY need the fix it
    helps provide. =) Email me at the address provided in my original
    email (exploit _AT_ guidoz _DOT_ com) and I'll provide a link to the
    batch files and such so you may modify them as you wish.

    Sorry for any confusion with the AV. I should of warned about that in
    the original email. (Others have written me asking the same question.)
    I only provided it to possibly help others who have lots of friends
    asking them for help to patch their systems. This simply sees if they
    are vulnerable, then leads them through the steps to patch the system
    if they are. (You may have to tell them to ignore AV warnings, or
    disable the AV scanner. Again, I urge you to test this on a
    NON-PRODUCTION machine first. See what it contains, read the batch
    files, see what it downloads, etc.)

    Please feel free to ask me any questions. Hope it helps someone else.

    Peace. ~G
