Today the funniest thing happened here: I received a spam (tagged as spam by SpamAssassin) and a message warning me that the attachment of such spam had been removed because it had a virus.
The server the spammer used to send his messages checked them for virus and found one, removing some .EXE file that was attached (theoretically, I had to install such file to have access to the most beautiful nude girls). :-)
It made me think: how many spams are infected with virus?
