McAfee wants me to reinstall OS High Sierra.
I just installed McAfee. It found a couple of "Spyware" links - the same ones for three days. When I tried a full scan, it didn't stop - millions of items searched and 160 "threats". It was in my backup at this time. Help from McAfee was long and sketchy. Their product would not install properly. They tried a "Trial" product to no avail. Their "Solution" is to have me reinstall the Mac operating system. Yikes! What to do? Is there a solution? I am hearing mixed messages about whether or not virus protection for a Mac is even necessary. Help. I am a long term Mac user and have six Apple devices.
iMac, OS High Sierra 10.13.2
