My laptop: Sony AR250g Win. XP Been using MS OneCare but my sub. is up. Also use Spybot and Ad-Aware and CClearner. Only complaint about OneCare is it's not very interactive, maybe a good thing, No News is good News, but should I be concerned? I need full protection and this sony seems fast enough to handle a large virus program without effecting the speed/performance. I don't want a bunch of different software, just one that will keep an eye on everything and keep me protected.
