Hi gang,
Finally got my first personal experience with a non-email virus last night, and 4-home was right there to catch it in the act. I was downloading a web page when avast's warning kicked in, and it's probably safe to assume that's where it came from.
I forget the specific virus, or the particular file, but it was an EXE in the Windows\Temp directory. My first reaction of course was to "repair", but I was told it was unavailable in the VRDB. So considering its location, I gambled and then chose delete-permanently. Ran a fresh disk scan afterwards which looked clean.
It was only this morning I discovered the rest of the "goodies" it had left behind. My first hint was when I started IE and it immediately loaded a strange page, rather than my usual blank "home" page. Aha, a hijacker at work!
So I dropped back offline, reset the home page, and let Ad-Aware do its thing -- it found quite a few "malware" items which I let it delete. Then JV-16's registry cleaner which turned up a couple of references to that EXE, and I trashed those too.
One more avast scan, thorough this time to be certain, and then I generated a fresh VRDB.
So proper cleanup really needs a triple-barrel response -- avast, of course, plus adware scanner, plus registry cleaner. That's been said many times here in different forums, but I'll definitely add my confirmation to that now.
Best to all,
Mike
