Re: All AV software eats pretty much all available CPU + 10%
Not all of it. Back in the day I used and recommend software called E-Safe. It had a very light foot print and never let any of the bad stuff in. It was so paranoid it wouldn't even install it's own signature updates without your explicit approval after the file was downloaded. People tended not to like it because you had to spend a fair chunk of time teaching it how to handle things. At some point I had issues trying to get a license for it and switched to something else, so I can't speak to how well it works these days. Back when I was using it I think they were based in Israel, these days they run out of Seattle, Washington.
