Small question, I just opened up an e-mail that has been on my computer for the past two months, avast popped up saying it was a virus "Win32:Trojan-gen. {UPX}". I don't believe it was a false reading as I am pretty certain the file that was attached to it was a virus. Deleted it. But my question is, that e-mail has been sitting in my Inbox for the past two months, how come Avast hasn't picked it up before? Are Email folders not scanned, durring an anti virus scan?
