My neighbors had McAfee and called me over when they were having multiple problems with their computer (compared to everyone on this forum I consider myself to be a computer idiot, but they think of me as a computer genius. Next to them I guess I am, but please don't tell them the truth
).
I suspected McAfees was at least part of the problem so I uninstalled it. I didn't want them to be without an AV so I installed avast! as a "temporary" free solution until we found something "better". I actually considered suggesting they try Norton.
Anyway I never found anything better and after a few days I got rid of McAfee's on my own computer and went to avast! My neighbors still have avast! even though they recently got a new computer, and they still think I'm a computer genius.
