I use mostly freeware... Avast has been fine for me in the free version. The paid versions advertise extra monitoring of various sorts, but in 2 years, I have 'maybe' 4 alarms go off where Avast said I was accessing a dangerous page. When I run the scan, or MalWare bytes, I get very few problems....mostly 'tracking cookies' that want to report where I go.

I NEVER intentionally go to gaming sites or 'warez' sites where malware hides behind every tree.
