Hey, stevet92. I use BITDEFENDER TOTAL SECURITY. It was top rated by Consumer Reports. It caught a couple of those pesky pop-ups before they could do any damage and gave me a chance to delete them. In addition, BTS doesn't slow down my system like Norton or Windows Live One does. Of course, that is not to imply that any and all protection programs will stop every malicious attemp to infiltrate your system. BTS seems to work as far as I can tell due to the mere fact I haven't had any problems since I started using BTS. On the other hand, if you don't get any attempts at intrusion how do you prove your negative protection is actually working???
