Did Mcaffee do it's job? Most people use free AV and some are satisfied. In case you're looking for comparisons,
here's a source I like to refer to.
In my opinion, the strength of your AV software is not really relevant. I have all Windows security features (defender, firewall, etc.) off except for "important" updates, of which I decide which to download and install. I use Comodo Firewall (Free), which comes along with a free AV as well. I don't rely on it's AV, but it's enough to warm me if a certain file happens to be suspicious, and even then I usually ignore it because I know where I'm downloading stuff from.
As far as my system is concerned, having AV is redundant, because I trust my behaviour. I guess the question is, do you trust yourself? Do you need protection? How much do you need? If you visit random porn sites or download stuff from unknown sources, you may need to take some precautions. Otherwise, I believe AVG free is
more than enough. IMHO
