OSX/Hovdy-A
Sorry, Mac users, but you're in danger too. This Trojan affects computers using Mac OS X 10.4 or 10.5, and lets the bad guys use your Apple Remote Desktop agent for a host of disturbing activities. The virus can be used to monitor your keystrokes, transmit passwords, turn on file sharing, take screenshots, and, creepiest of all, take pictures with the built-in iSight camera -- all unbeknownst to you! It's spread through downloads that you have to agree to, so if you stay sharp, avoid sketchy utilities, and keep your anti-virus protection current, you'll be fine.
