Recently one of my Centos servers was infected with coin minet, linux is not always safe.Well,I use Ubuntu
I haven't installed one yet (it's been 3 years)
I use Zonealarm Extreme Security 2018 because it contains a lot of settings giving me a little more control of my systems.I use Kaspersky my pc is great and kaspersky uses extensive resources but I choose them just because they are RU origin.I believe the best bet is going with original anti-hackers.
Whats yours?
