SpywareBlaster doesn't scan and clean for spyware - it prevents it from ever being installed. By setting a "kill bit" for spyware ActiveX controls, SpywareBlaster can prevent the installation of any spyware ActiveX controls from a webpage. It does this while not interfering with "friendly" ActiveX controls - so your browser can work correctly and you can have peace of mind! You won't get any more annoying "Yes/No" boxes popped up, asking you to install a spyware ActiveX control (which can increasingly be found in pop-up ads!). In fact, Internet Explorer will never even download or run the spyware ActiveX control! In addition, SpywareBlaster can prevent many of these spyware ActiveX controls from running, even if they are already installed on your system.* The newest SpywareBlaster version can even block spyware/tracking cookies! And SpywareBlaster does not need to be running in the background to provide this protection! The SpywareBlaster database contains information on these known spyware Active-X controls. Make sure you run the Check For Updates feature frequently to get the latest database! (And make sure you check the new items to protect your system against them!) SpywareBlaster also provides the exclusive System Snapshot! - Take a snapshot of your computer in its clean state, and use System Snapshot later to revert many changes made by spyware and browser hijackers!
