What does the Internet know about your personal life? Well, a lot: Viruses called spyware know which websites you visit and for how long. They know what you click and what you like. Spyware can even record your personal information or slow down and crash your browser.
Kill this menace dead with Spybot - Search & Destroy. It protects your privacy from spyware and adware and keeps your personal information where it belongs - with you. The program's Immunization feature blocks access to sites that contain malware, spyware and other nasty software and will also block cookies that are designed just to track you.
Spybot - Search & Destroy can scan for problems on your computer caused by malware and rootkits and fix them, too.
