BGPKiller is an ad killer (or blocker) for your Avira Antivir antivirus. The application is designed to stop popup windows (i.e. ads) coming from Avira. It monitors the unwanted Avira processes responsible for ads, and silently kills Avira popups and ads before they show up. BGPKiller runs alongside Avira Free Antivirus, in your System Tray, and tells you each time it kills!
