Security Suites. Any good ones? I read a review from about 1 ½ years ago, on how none of the suites were nearly as a good as a smorgasbord of independent packages. As I have this gut feeling that the fewer the system sources on a computer, the less chance of incompatibilities and conflicts (and of confusion on my part about the army of programs and files that computers like to spawn), has this changed? Ie, is there currently a good combination Firewall, ad blocker, scumware cleaner, and (possibly) anti virus program? PS What exactly is a hardware firewall? Is it only for networks, is it expensive, what does it entail for the ordinary non-technical home user? Thanks for any info/opinions.
