My internet access has been freezing lately. I've switched back and forth between Internet Explorer and Google Chrome. Sometimes it goes through and other times freezes. It's getting frustrating. Any suggestions?

Another problem. I have Norton Security. Occasionally I get a warning that my CPU Usage is High and it will report Comcastantispy.exe as the reason. AND when I shut down my computer I get a message that Comcastantispy.exe is causing a problem. I've searched for Comcastantispy.exe and it is not on my hard drive. WTF! Any suggestions?
