Avast EXE files are being deleted

[karapuz]

My ashavast.exe file is being deleted all the time. I've read the topics concerning the problem but none of the solutions suggested helped me.

Welcome to the forum karapuz.

Can you tell us what solutions you've already tried.  This may give some clues and will help us avoid duplication of effort.  And what is your operating system?

Did you follow the suggestions there?

Seems you need a full cleaning of virus and rootkits (hidden virus).
I suggest you visit this page http://www.antirootkit.com/software/index.htm for antirootkit detection, removal & protection.

Full computer on-line scanning:
Kaspersky
Trendmicro housecall
Ewido
F-Secure
Spysweeper

I tried some online AV scanners like Kaspersky or Panda but during the scan the PC suddenly reboots. I also tried to run it in Safe Mode but it is not working...

Have you tried F-Secure Blacklight yet?  If not download it here and run a scan

Make sure to close other programs before scanning and don't open anything or surf the web while the scan is in progress.

Thank you very much, it worked! It was a virus called I-Worm/Bagle

I wish avast was able to detect and avoid infection of this worm  :'(

[igor]

Don't you happen to still have a sample of the infected file?
We would also like to detect it, of course... but we need the sample first.

Avast doesn't detect Bagle/Beagle? this has been around for a year and half!

Bagle/Beagle has lots of different variants

Not this particular variant that is a bagle rootkit variant, which is hidden from the usual detection methods.

Igor, i sent a link to vlk, but i am not sure did he get the email from me 
In that link there is a sample of Packed.Win32.Bagle, i think that there are more samples of bagle there because i open the list  and did fast search and there were listed a lot of them.

Vlk was in British, then in Italy, now avast program is being updated... I'm not sure he has that much time right now... Just to let you know

Thanks Tech but it would be nice if someone vlk, or igor tell me if they liked that link, so i can know in future do they want me to send them some nice samples of malwares, or if they are interested in some malware so i can try to find what i can.
