After 3 months of flawless operation my new Dell with XP and Norton Internet Security 2005 suddenly would flash ccApp.exe error message and then take about 5 minutes to shut down (several times it had not shut down after 30 minutes, so I hit the off button). I contacted MS which had a canned message to go to Symantecs (Norton). MS had obviously had this problem before. Symantec said that the ccApp.exe file was critical to Anti Virus program and to reinstall. I have done that and still have problem. Symantec suggested that I contact Dell. Dell says it is not their problem. Anyone have any ideas??
