My antivirus prgm expired this am without me noticing.

What is happening now: i tried to download the free AVG version but the moment i click the web site from google, my IE or firefox will shut down automatically. But I can still browse web page of any other sites, so long it got nothing to do with antivirus prgm download.

Alternatively, I tried to install the antivirus software from disk (ahem version), but the moment i click the program set-up, the window explorer just close by itself and there is no way that i could install any progm.

What's happening?

What do i do now?

Thank you!

Very informative, but how sure are you it's mydoom?
There are tons of virus that has the capability on modifying hosts file to redirect once you reach a AV site.

I agree with eXPeri3nc3. But assuming that the TS mentioned about unsuccessful installation of AVs. I guess, it is possible to deduce which type or which malware in particular is playing pranks.

Anyway, TS, please post a HijackThis Log. No point keeping us all in a limbo.
Cheers!

thanks all ... sorry for this question

how to go about and get this Hijack This Log?

I had mydoom before, so when reading this thread, i assume it's mydoom, anywhere it's no harm to try.

Download the File from here.

Scan then create a log. Please attach it. Cheers!
