Best Antivirus 2017?

[BusyGURU]

Has anything changed since 3-5 years in the antivirus preferences? I've checked http://www.av-test.org and it looks like Avast, AVG, AVira and BitDefender are still on the top positions except for "AhnLab V3 Internet Security 9.0". What is it? Never heard of such antivirus. I personally prefer bitdefender total security 2017.

And according to http://www.av-comparatives.org July – November 2016 tests F-Secure is the best, then follow Avira, Bitdefender, Trend Micro and the 5-th position is Kaspersky Lab. So the question is how can be such a big discrepancy between two independent labs?

Haven't heard of ahnlab either, looks very suspicious... I use free avast antivirus and quite happy with it :-)

It all depends on the testing and rating parameters.
