the free version is really damn ok
but i would recommend to upgrade to PRO, since you get hourly virus patterns and not daily patterns on the free version.
but cylance AV and paolo alto AV > all
even trend micro is nice and cheap, but you have to configure a damn lot stuff, so i would not recommend it
norton and kaspersky are just cash graves and pretty slow on virus patterns.
I use Crypto.VokAin AV, the best of the best
