This is very easy
Undoubtedly 360TS, I disagree with the policy of Comodo, not having as much attention as it should on your AV engine, which by the way walking in decline, just think of proactive defense (I know it is important, the future of the suites, most can not forget there are many lay users). Qihoo is very fast, easy to set up (more languages lacking and fix the bug of Avira and Bit engines do not update), excellent detection in doubt, provide reasonable proactive defense, strongly recommend.
I would never use Comodo Av, I prefer to Windows Defender, maybe give it a try for your firewall. Qihoo wins this contest with large clearance This is my opinion #
I also recommend ESET or Emsisoft ...,
