Chuck's Norton 360 Anti Virus has expired, and now he can't get it off the system. Since he hasn't renewed it, it's messing with his internet connection. Leo says that Norton's anti virus suite is notoriously overzealous. Anti-competitive and predatory? Maybe. If he needs to get rid of Norton AVS, Google Norton Removal Tool. They have a very good tool that'll remove everything and will restore his computer. Get a better antivirus program like Eset's Nod32, or if he doesn't want to pay, Microsoft's Security Essentials.
