New types of spyware are becoming increasingly malicious. For example, CoolWebSearch changes settings in Internet Explorer browsers and installs rogue applications; KeenValue collects information about users and sends advertisements to systems on which it resides; Perfect Keylogger logs every keystroke users enter, putting users' personal information at risk; and Marketscore collects all data sent to other systems. The Computer Protection Program strongly recommends that all Windows users run an anti-spyware program such as Spybot every day. Free copies are available on the Lab's download site. Be sure to read the instructions before you run this program. One site contains a list of free Windows software that has no embedded spyware or adware.
