Sircam is rated high-risk right now. It will spread by email using addresses from Windows’ address books, attaching a random file from the “My Documents” folder. Yes, I’m sure you all want your private files circulating around the Internet! It also does more nasty stuff, and I adamantly suggest that you read some first-hand information to protect yourself (and your friends).
