Like I said I've tried Sophos ealier and used it for about 4 months. I was happy with it then, but I went to Norton then since I got a license for that. Sophos isn't that bad. It has great signatures and there is behavior detection/kind of automatic Hips in Sophos home. It runs very light and smooth on my system, so I'm happy
I've used Avast and Avira for quite some time on another computer, but I didn't liked that Avast isn't as light as it was earlier. And Avira now comes with that stupid launcher that is eating memory and still lacks zero day protection. And chinese AV's, there is something in me that refuses to completely trust them.
Well, I've tried almost all of the AVs there exist during the past years and now it is Sophos turn. Might change again in the future. BD free looks promising too
