I know I may seem paranoid, but I know for a certain that my AntiVirus software (avast) runs in the background. I determined this by opening my task manager and seeing that their firewall was running. They also displayed an ad once. I know Avast is thought to be a 'reputable' program, and I truly want to believe this. Can/are they just tracking my web activity, and compromising my personal information? Perhaps like a keylogger? Thanks for the help in advance.
