Ad Arrest Popup Killer uses an advanced, 2-filter system to block pop-up advertising from Internet Explorer, Kazaa, Morpheus, AOL, Gator, and chat programs such as ICQ, AIM, Trillian, MSN, and Yahoo Messenger. It will also prohibit spam ads initiated through your browser by spyware, adware, and virus programs. The software requires minimal resources, and it will not conflict with personal firewalls or anti-spyware programs. Ad Arrest offers a simple hotkey system for managing your whitelist, so you can tailor the software to your specific browsing needs.
