The Security Mentor

You know those ".PDF" files that you see everywhere? The program that reads them has a security flaw. This affects you no matter what operating system you're on, and the impact is that opening the wrong PDF might let the file's author take over your computer.

Adobe, the author of the reader program for PDFs, has published a fix. How you install it depends on what operating system you're on. Start at Adobe's security page to hunt down detailed upgrade instructions.
