I tried Avast anti-virus program. It is memory hog, finding that
out I dumped it. Did not cost any $$. Worst is they try to come
into your computer with your permission of course saying they need
to get in there to fix the problem.

I've been using Avast Free for years and nobody had ever tried to do
any such thing.

Memory use is on par with or better than most other anti-virus
solutions I've used. Right now, Task Manager reports that it's using
about 35 MB or RAM.

I don't think you know what you're talking about.
