What is the best product for speed, least false positives, prevent infection, ability to clean the virus once computer is infected? My choices are NOD Smart Security, Kaspersky Internet Security, Norton Internet Security. I want a security suite, but I'm most interested in the virus protection, feel free to suggest others as well. I am currently using NIS 2008, I was using KIS and I still have a license but for some reason it was causing my hard drive to make a lot of noise, so I had to uninstall it, since then I had to reformat machine, so perhaps I will consider it again, I never installed NOD Smart Security, but I understand it is an excellent program. Anyway I will be waiting to hear what everybody says. Thanks, Billy S.
