For years, removing ad-serving software (often called adware or spyware) from your desktop has been the job of one product: Ad-aware by Lavasoft. But there's a new game in town. PepiMK Software's Spybot offers a wealth of useful features that, frankly, should send Lavasoft back to the drawing board. Spybot delivers useful tools such as an email list of opt-out addresses to stop unwanted solicitations and a file shredder to securely overwrite unwanted files deleted from your PC -- all of which Ad-aware Standard Edition lacks. Best of all, Spybot does it all for free. For protection against ad-serving software, Trojan horses and other means of tracking your surfing habits, get Spybot immediately.
