Miners are often recognised as viruses. Don't worry. Just make an exception in your AV software.
Or one good question, why you need AV on mashine what is used for mining?
Every AV can take 30-40% of your CPU so i would not have AV there.
This is simply not true! Antivirus is a must on every device connected to the internet.
No, what you said isn't true - AV is near worthless if you know what you're doing.
Key word is "if"

Think about a condom

Its not required if you know what you are doing

But when it comes to an intercourse with a stranger you better have it

I am managing 1000+ workstations. Kaspersky Endpoint is using less than 1% of CPU. Daily reports contain 100+ active actual threats.
