Cool Web Search is a deadly spyware program that was just discovered to be tracking keystrokes of millions of computers. If you have this program secretly running on your computer, your passwords, bank information, credit card data, etc. could all be logged and sent to crooks. Take a moment to run CWShredder from TrendMicro.com to scan and remove this nasty program from your computer. Click on the "Remove CoolWebSearch" button to run the program.
I also use Webroot's Spysweeper software and Adsense to help keep my system clean. Other suggestions?
