On my home system, I keep Avira AV and Comodo Firewall.
Avira appears to have become some kind of subscription service, when I downloaded and installed it on a troubled computer recently, asking for a user account and password. Comodo is a product I've personally come to enjoy, but after setup, it prompts for EVERYTHING. And even after it's setup and running, you'll still get prompted (bullzip pdf, for me, seems to trigger it every time).
What recommendations can you give for silent, plug-and-play kinds of AV and Firewall, that I could install on the computer of a senior citizen? I need something that just passively blocks and scans on a regular schedule without much user interaction at all.
I took a quick look through the sticky topics and didn't catch anything as specific as my request (or maybe I just looked for it in the wrong ways). Could you guys offer some suggestions, please?
