Heads up, Skype users. Seems there’s a P2P worm that’s working its way through the chat feature. It appears as a link from someone in your contact list or possibly an unknown user. It’ll look like a JPEG file but when you click on it you’ll get a dialog asking you to run or save a “.scr” file. If you run it, jump back Jack. You’ve just been infected and your computer will start sending the infection on to your other contacts.

Symantec, F-Secure Corp., and Kaspersky have already updated their virus definitions and other antivirus software companies should follow suit shortly. In the meantime, don’t download that file!
