Greetings. For many years I used Norton Antivirus with complete success. I never had any problems with the software and it always kept my computer clean and secure. About a year and a half ago I moved and signed up with Comcast for my ISP. They offer a free version of McAfee's Security Suite to all their subscribers. Well, I figured why not try it out since it's free? So I switched to McAfee and have had nothing but problems with the software ever since. Although it has kept me free from viruses, it crashes every other time I turn my machine on, has a clumsy interface, is very slow, and sometimes won't even open. I've decided to ditch it and go back to Norton, but I know there are a slew of other free security programs out there these days. So, my question is: Is there a free antivirus program that works as well as (and is secure as) Norton? Or a combination of programs that could be used? What's the best option(s)? Many thanks in advance!
