Probably a bit weird, but I love finding the Sircam virus in my email. I've received 6 virus emails already in a three day period. They are easy to spot...rather big email size, usually a real name of someone I don't know and a one word subject that doesn't seem to be selling anything. Of course, it's obvious once the email is opened ("need advice..."

. I send replies to them to let them know they have a virus with a link to Symantec's site about the worm even though we're told not to. They have never replied though.
Now don't go sending me viruses...I only like them when they aren't deliberate.
