SpywareBlaster is the original anti-spyware protection solution!
Developed in 2002 to help users prevent spyware installs, SpywareBlaster pioneered the effective use of prevention techniques to reduce or greatly eliminate spyware-related problems, as well as problems related to other unwanted software such as dialers, browser hijackers, and adware.
Today's SpywareBlaster is greatly enhanced - protection is still the foremost purpose of the program, but it also provides unique utilities like the exclusive "System Snapshot", and various useful tools. The interface has been upgraded to provide easier access to all of the new options, including Restricted Sites Protection, and Mozilla/Firefox Protection.
Help keep your system safe and secure with SpywareBlaster. We hope you like it!
