    Hello everyone,
    I'll get straight to the point, I've never seen a virus so bad on my comp :

    Symptoms (by observation order) :
    -Slow windows startup, sometimes seems to freeze completely.
    -impossibility to access drives through their icons (but ok if opening a sub directory and going up for example) (until action number one, see below)
    -visual glitches everywhere (now gone, by itself it seems or maybe after first operation, see below).
    -impossibility to install certain programs, namely Symantec Anti-Virus, Kaspersky online and bitdefender online. Sometimes a message "you may not have the administrator priviliges" comes along.
    -popups, numerous attacks on different ports, publicity banners on internet sites replaced by adult/other banners.

    Defense :
    -only ZoneLabs ZoneAlarm, always worked perfect for me.

    Actions :
    -simple deletion of autorun.inf and boot.com that installed themselves on every drive-> Symptom one and two disappeared
    -scan by Ad-Aware 2007, Malwarebyte's Anti-Malware, Flash Desinfector and HijackThis -> Nothing interesting exept maybe "dumprep 0 -k", command "%systemroot%\system32\dumrep 0 -k" . I just deleted that from start-up via msconfig.

    Computer Configuration :
    Windows XP Pro SP3, running latest IE and latest FireFox.
    Dual boot with Grub on Ubuntu, but I don't think that matters.

    Attached is my HijackThis log, but I think it's clean. Nothing strange in my running processes either. I'm willing to install ComboFix or whatever, just please keep in mind that I'm not a pro-formater and that I have important data on the PC, and,

    Thanks a lot for any help :)
