I am a member of a computer self help group of about 100 people.
With just a couple of exceptions we all use AVG free version.
The couple who do not, have not tried AVG as they are happy with what they have.
As for the remainder of us, most have encountered problems of some sort with other anti virus programs. The worst of these has been Norton, which takes up a lot of space, is intrusive and very, very difficult (worse than most viruses) to delete.
AS a 'belt and braces' addition, I also use IObit 360 Security too. The two programs do not appear to conflict.
