I guess I've just been lucky. I've used McAfee for years and never had one ounce of trouble from them. They have continuously outperformed Norton every time I've tried a comparison. No, they dont find EVERYthing, but no service does, in my experience. Maybe there is one, but I've never tried it. Of the A/V programs I've used, Norton has always been the worst. Of course, I keep the Internet settings pretty tight too, and complement my A/V with a router firewall, software firewall (also McAfee) and port manager. I've had ONE virus sneak thru in the last year, and while McAfee couldnt get rid of it for me, it did at least detect it (which is more than Norton did when I tried it as a comparison). I suppose it must depend on what you are exposed to and perhaps location (or maybe just what ISP you use), but I rarely even see people ping me anymore, let alone have to worry about anything getting in. And if it does, it dont get out again.
