I have an unknown program that terminates my antivirus software. A message comes up every now and again that a program wants to terminate Avast and asks permission. If you click no there is no issue. If you leave the box unanswered it terminates the program automatically within five minutes, so if you are not there to see the pop up your antivirus terminates. I have run the antivirus; nothing. I have switched antivirus programs; same issue. I have checked for malware, adware etc. and searched for unfamiliar programs but no luck. I have run cc scanner, and a registry cleaner but still no luck any other suggestions?
