I use AVG free version and I was quite happy with it until read this thread.
I just ran HouseCall and it found Mydoom.dam in one of my zip backup files
on my backup partition. Before deleting it I then ran AVG on the infected
file and it found nothing.
Now that's a definite worry :-(
Strangely, the virus wasn't present in the original files.
