Privilege, I would agree with mandy123 first start with the budget, ask what you want from antivirus because the majority has additional features built in, and then check out the reviews of the software there are a bunch of them online like PC mag and such (I cant guarantee its not paid, not sure). The thing is we are all different and some of us will never be satisfied with software because it gives one and lacks another, there is never a perfect solution. Take care
