I can tell you straight off Norton is liked by your folks cause it was one of the First
Anti Virus programs
The program was rated Number one for many of years ,I'm not going to lie I used Norton many times Win 95 through 98
Then I used Mcafee , I started Noticing Norton Blocked alot of content that was never harmfull ,it actually became a pain in the butt you basicly had to strip it down to do what you need too with out all the alerts
Mcafee same deal ....
I use Webroot spysweeper been useing it for years now ,don't mind paying for a Anti Virus but they also shouldn't cost over 25 Bucks Norton /Mcafee and a few Others are seriously OVERPRICED !
There is No ANTI VIRUS worth 60 to 80 bucks a year That money could be used for other things
I agree with the free MSE but it only covers so much but then again if you only do light work not downloading from other linked sites and keep it to the trusted one's you should be good
But if your the Adventurous type and don't know any better it is smarter to stick with what your parents had installed that way they can't blame YOU if the wrong thing went down
Makes sense right ?
