Yes - me too.
AVG8 found Crack.S in my adobe creative folder plus:
I-worm/Netsky and I-worm/Netsky.D
Now it found this in an old email, cos it was also in an old backup ie. it must have been one of those emails that never got moved into a folder.
Strange that AVG7 had never found these so called viruses, as it was regulary updated.

explains that this family of threats are basically email senders.
Now the problem is how to separate off all the emails - maybe create say 4 folders, to each contain 25% of the emails, and then scan them, then repeat with the infected folder until the specific email message is found.
But either way - well done PaulW - I was beginning to think that me and Jacques were on our own.
Cheers mate!
