Well in a sense I agree with bob3160 that because of the nature of the Internet itself we cannot expect to have much or any privacy left.
The Internet is being kept available just because users can be ad-fed, tracked, profiled, fingerprinted and come under surveillance.
All these data is going to land on some big corporation’s desk and will also be stored and analyzed by governments for whatever reason these may have to do this - this is called marketing and mass surveillance. The user that agrees to take part in connecting out to the Internet has a very, very hard time to avoid privacy intrusion or the total lack of his or her privacy. You just could be fed the wrong certs or a specially crafted update and your computer could already have been compromised for an investigation by some government institution. Cyber-police assume they should have a legal right to break into computers.
Blaming an av solution for this general situation is just barking up the wrong tree. The discussion should be held some place else, but I see that a larger part of the population is reluctant to question this situation and rather would accept the situation as it is.
