One such free utility is SpywareBlaster by JavaCoolSoftware. SpywareBlaster is unique in its approach to protecting you from spyware. When it's launched, SpywareBlaster adds known spyware-distributing websites to the "restricted sites" section of Internet Explorer. In doing so, it disables features of the browser, such as ActiveX and Java, that permit the installation of spyware in the background, often without the end-user's knowledge.

SpywareBlaster also checks Internet Explorer's security settings, and if needed, offers to set them to a more secure state so applications cannot install in the background without first prompting the user for permission.
Figure 2: SpywareBlaster shows you the current security settings of your browser, and its recommended settings. When offered, clicking the Set Recommended Values button will configure your browser to a more secure state.

It offers you the ability to disable ActiveX as well, to prevent advertisement and tracking cookies pertaining to the sites listed. Ensure that these settings are enabled to decrease the likelihood of becoming infected with spyware.
Another feature SpywareBlaster offers is the ability to lock down your home page settings so that it cannot be overridden by spyware in an attempt to hijack your browser.
