I have used Zonealarm Pro (this is a Firewall program) for several years and so far have not have any intrusions. I also switched from Norton AntiVirus to NOD32 offered by a company named eSet. I had used Norton for over nine years and until version 4.0 I liked it fine. That version would not install correctly and after three months of correspondence with some tech that was in India, I read about the NOD32 program and used their FREE trial version. It immediately found a possible Trojan on my system that Symantec and several other virus programs did NOT find. After ten days of the 30 day free trial I purchased the program from eSet and love it. It automatically updates the latest virus definitions daily and installs them. It can do a full scan in five minutes versus Nortons of about thirty minutes.
I get no Pop-ups here.
