Along with firewall and antivirus programs, anti-spyware is a security must-have. Spyware is a particularly unpredictable type of threat. It can trigger pop-ups or cause your computer to slow to a crawl.

Even worse, spyware can work in the background without noticeable symptoms. You should use a few anti-spyware programs to ensure that each possible threat is detected.

SpywareBlaster is an effective anti-spyware tool. Unlike most anti-spyware programs, it does not scan the hard drive for spyware. Its strategy instead is to prevent modifications of your files and settings. For example, it can block browser toolbars from installing themselves.

SpywareBlaster can be used to prevent changes to Windows' HOSTS file. It also has a System Snapshot feature similar to Windows' System Restore. SpywareBlaster will report any changes to your system since the last snapshot.
