What is CA Pest Patrol Realtime Protection?

it comes bundled with Comcast constant guard. It is used for the Comcast toolbar for anti-virus protection. If you are running an anti-virus suite I would delete it because it uses a lot of cpu and also it will interfere with your security suite and slow your pc down. P.S. if you cannot delete it use REVO uninstaller! then go to 1] C:drive 2]Program 86 files 3]common files 4]scanner file and delete that ca pest file
