How did you finally determine that? Did Avast send you a full report or did
you upload it to Virustotal? Were there any symptoms of the infection, ie
were there any registry strings added, any unusual additions to a hijackthis
log that you hadn't seen before, or were any files added to your OS
directory?
What's always puzzled me is that since these AV programs are scanning files
so quickly, are they actually "reading" every file or are they just checking
the filenames against a definition database.
How many AV programs actually can clean the registry and OS/programs
partition(s) of all the remnants of these trojans/viruses? Is just deleting
or quaranting the offending file enough?
If you read the Symantec manual cleaning instructions for any given trojan,
there's quite a few areas that have to be cleaned.
