Win 7 x64 SP1 and Avast 6.0.1289 Win XP SP3 and NIS 2011
This is one of weirdest things I have seen in a while.
I have 3 HDDs; one contains WIN 7, the other WIN XP, and the third has two partitions - one for XP image backups and one for Win 7 image backups. All images were create from Paragon Disk Manager Server edition from a bootable WIN PE CD. I have used this CD for years with no problems.
I scanned the partition containing the WIN XP images today and Avast found multiple files all infected with Win32-Hupigon-ONX[Trj]? Now I don't know how image files can be infected? The XP system was clean when I always did my backups. So I thought these must false positives.
So I next scan the Win 7 backup partition that contains image files. Clean. Now I am really worried.
Next I scan my XP drive from WIN 7. It finds some "global" bad guy in the page file. So I delete the page file.
Finally I take an image backup of the XP drive which should be clean. I then scan that image backup and guess what? It finds files infected with Win32-Hupigon-ONX[Trj]. Now how is that possible?
What the heck is Avast doing here?
