All of a sudden, i opened today my PC and neither Kapsersky nor Zonalarm loaded in start-up. I tried to run these two programs by myself but the same message pop-up: "zlclient.exe is not a valid Win32 appliction" and "avp.exe ...." I tried then some other programs to run, and everything is ok. BUT, every program that is related with viruses, spyware and so DOES NOT RUN!!! So, the same message (valid win32 application) poped up for Spybot S&D and Spyware doctor too! Is it accidentaly that these programs do not run? I don't think so.... I start-up with win98(2nd boot) and run kaspersky from there. It did not find anything. Also, i searched for mysterious loads from msconfig and other start-ups or loads....and found nothing. i have never seen something like that. The classical problems are usually handled the ways i tried, but what is this?
And guess what...Safe mode is off the game: As soon as it loads the .sys files it restarts by itself!
System restore does nothing at all. It works, but identifies says that nothing has changed.

O, and hijackthis also faces the same problem (not valid win32 appl.)!!!

Sounds like the Bagle rootkit

Go to the Malware Removal forum and read all the sticky threads. Then make a topic there

I have this problem as well. I was wondering how you fixed it.

i would assume by following the instructions given in the post above yours
