>Or horrible (in my opinion) paid solutions like McAfee...

It's not just your opinion. Mr. John McAfee himself, the guy who started the company and whose name it still bears, has publicly stated that McAfee software is "the worst software on the planet"!

If that isn't enough for people to avoid a brand name, then I don't know what is. But apparently, countless businesses are so clueless they keep using McAfee software even though its own founder says it's trash.
