It's funny, I had a 5+ year old desktop HP computer and was having some problems which HP (smart friend service fixed)..She..the tech noticed I was not running any Anti Virus except for the Windows Defender... and told me that Norton was the best.. I downloaded it and my hard drive died a few months later which made the computer about 6 years old... It wasn't because of Norton's software, but the computer had a lot of use watching baseball games and lots of software handicapping programs for the races. I bought a new HP computer and the free Anti Virus which came installed was by McAfee. I hated it because my Email program would not run with some setting that I could not fix, so deleted it and am using a free Avast program, which is not bad, but constantly wants to sell you something. Malwarebytes is my favorite paid thing.. The paid version stops webpages that are infected, the free version does not.. Funny how HP went from Norton to McAfee in a short time.
