As the title says, looking for some good and free anti-virus; that doesn't have ads or pop up's.

I currently run AVG AV Free Edition 2015, but ever since last Oct when I tried the Pro Edition features out, I get a pop up about 2-3 times a day, AVG Zen I believe is the title of it, about upgrading to Pro; if AVG is the best free AV to have, anyway to stop the pop ups?

Also use Spybot: Search & Destroy 2.4 and Malwarebytes Anti-Malware (Premium) for spyware and malware needs.

In my first big WoT clan, someone posted using those three things from above was total coverage; course that was like 2-3 years ago.
