Sophos right now I don't care for, also it can really slow browsing.. InterceptX with integrated HMPA may prove interesting. Panda is lackluster, especially for PUA in my experience. I like Emsisoft, and currently have 10 PC 3 year license, it's effective with A2 and Bit engines and a really nice Web Scanner that picks up things most products do not. However I have found the software can be buggy at times as the only downside. Emsisoft is ridiculously good at finding PUA though.
Actually my 2 favorite AV's are Emsisoft and Trend Micro. Since I have Bit Defender on the gateway, I tend to lean to Trend for blended protection.
Zemana was always there because it was very lightweight and offered 5 additional engines.. Now? Not so sure.
Yes, I've recently noticed that Sophos can slow down my browsing. It's still beta, so we'll have to wait to see if it improves until they release the final version.
I've been an Emsisoft user for a little more than 10 years, and yes, it can be buggy sometimes, but an excellent product.
In my recent experience ZAM did a better job than the products I've mentioned.
Let's see how it evolves into it's "Ultimate" version.
