Error returned again after uninstall/reinstall: "Symantec Service Framework encountered a problem and needed to close." Used Norton uninstaller. Reinstalled Norton Internet Security 2011. After a couple of good days, the messages are all coming back as soon as the computer starts. I am running Windows XP SP3. No other antivirus programs installed. For now, I am not closing the little window so Norton doesn't shut down. I appreciate any help.
