There is little I can offer except to uninstall the product, go get something else. Ask for your money back.
Several weeks ago I contacted Symantec Technical Support to help reinstall Norton Internet Security and Norton System Works and provided one of their technicians with remote access to my computer to assist me.
After updating and re-installing Norton Internet Security and then Norton System Works (Which runs fine, now) we rebooted my laptop. Once the desktop opened, an error message appeared:
"00516017.EXE Unable to locate component. The application failed to start because NUMISC.DLL was not found."
I left the error message up in hopes of bringing it to the Symantec Technician's attention-- To my dismay, as long as the error message was up, the computer would power off within 1 minute of starting up. I tried to reboot the computer three times with the same outcome (the desktop opening, the error message appearing, and the comptuer powering off). I finally clicked the "OK" prompt of the error message, and my computer then seemed fine.
As of several days ago, my computer has begun to power off unexpectedly and without warning. No error message appears, but I am convinced it is related to the NUMISC.DLL error. The computer will power off while I'm in the middle of browsing web pages, during Norton virus scans, when the computer is idle-- Any time. But there seems to be no method to the madness. There does not seem to be a specific time frame for which the computer powers off (though it seems to stay ON for at least 45 minutes or so), and there is no indication as to why it shuts down.
I am running Windows XP, and my laptop is a Sony Vaio VGN-FJ270.
I tried contacting Symantec Technical Support again, providing them remote access, but they seemed clueless. They emptied my "Temp" folder, opened up Norton, and told me the problem was resolved. Unfortunately, it isn't.
Any help to resolve this problem would be GREATLY appreciated.
