BettingSiteDefender is a browser extension which supposedly checks for blacklisted websites. However, it is found to be an adware that will fill your screen with unwanted advertisements. These ads are in the form of pop-ups and banners enticing users with fake coupons, phony software updates, surveys, tech support scams and the likes. Clicking any of the ads will send you to malicious websites to get money from you or infect your computer further. BettingSiteDefender will also attempt to commandeer one’s browser search and homepage. It may monitor your browsing history and prevent you from changing your settings back.
BettingSiteDefender is usually installed through bundled software without you knowing. Remove it immediately!
