I suspect most of us here are professionals, and AVG Free is solely for home/private use.
I started using the paid for version on my work machines some years ago. As AVG isn't perfect (no AV is) I also have the paid version of Malwarebytes, and I also use a paid-for Zonealarm. Touch wood, I've been safe so far. And having spent hours de-malwareing other peoples machines I appreciate having something that seems to work.
Spending a hundred quid or so a year on protection for my work computers doesn't seem that unreasonable.
Having said that...data grabbing at the level proposed by AVG is pretty shitty!
