Over the last couple of years, spyware has grown from being a nuisance into being an epidemic. Although many tools exist for fighting spyware, they largely focus on the recovery of infected systems and have been mostly ineffective in the war against spyware. A few weeks ago however, Microsoft unveiled the first beta of their own anti spyware solution. Although this software is capable of disinfecting an infected system, its primary goal is to prevent the initial infection.
It never fails to amaze me how hostile of an environment the Internet really is. The Internet is loaded with Web sites containing malicious code. Accidentally landing on one of these sites can infect your computer with a plethora of ad ware or spyware modules. The scary part is that you may never even know that your computer is infected. While its true that some ad ware and spy ware infections are obvious because of the way that they hijack your browser, often times key stroke loggers and other Trojans are working silently in the background where you would never notice them.
The worst part of spy ware and ad ware is how easy it is to get an infection. Not only are the owners of countless malicious Web sites doing everything that they can to deceive you into accidentally visiting their site, nowadays perfectly legitimate and otherwise harmless sites can spread infections. There have recently been reports of legitimate sites that sell ad space infecting PC’s because someone has imbedded malicious code within an ad.
