The Security Mentor

Apple's Quicktime media player has some security problems. Apple's finally released a fix. You'll be asked to install it within a week anyway, but if you play lots of video from the net I'd suggest doing the upgrade right away.

Go to System Preferences, the one with the icon like a light switch. Under System, choose Software Update. Click Update Software, and Check Now. Accept the Quicktime update.

Security firm Symantec reports that bad guys are using the Quicktime vulnerabilities today.
