They are the very opposite of necessary. The main thing they do is clog up and slow down the computer.Then the salesman persuaded her to buy either Norton or McAfee virus protector. I am not sure whether they are necessary any more. Isn't Microsoft Defender good enough?
There are anti virus products out there which are better than just relying on the built in Defender and Microsoft firewall, but those two aren't among them.
Something like Bitdefender is a much better choice than either of those.
