I Don't know how this slipped by me, but SpywareBlaster is up to version 3.4. It's should be part of your anti-spyware / virus toolbox along with Ad-Aware (ver. 1.06), Spybot Search and Destroy (ver. 1.4) and Microsoft Antispyware (beta). And if you don't have any kind of anti-virus software running, go ahead and download AVG Anti-Virus (free version, I've heard good things about it :)

Shortkeys is a text / paragraph replacement program using defined keystrokes. Download the free version and at least try setting it up to input your name. Did I mention that it's free?

Check out the Top Firefox Tips and Tricks from PC Magazine. My favorite is the update button. I never knew that little sucker was up there. Not only will it update Firefox but it also updates all installed extensions. Sweet!
