how i can reuse the norton 360 v Its trial period is expired. Plz send me product key or trial reseter. special thanks

Please remove the existing version of Norton program from the control panel, then go ahead and delete all Symantec and Norton files from the computer's C or D drive.

After that, open your registry and first take a back up just in case anything get deleted by mistake.
Then delete all Norton and Symantec files from HK CURRENT USER, HKEY LOCAL MACHINE, HKEY USERS, HKEY CURRENT CONFIG.

You can click on the SOFTWARE folder in each class to find the Norton files if any.
To open your registry editor, type regedit in RUN command (windows key+R)

After that you can again install a trial version of Norton for 30 days.

I picked up this program called personal antivirus and I can't get rid of it.i looked in my programs and it's not even there.Any ideas?

go to start menu, then go to "run", then type regedit and hit enter.
Now you are in registry.
Find the HKEY LOCAL MACHINE and expand it, then find Software, and expand it. You should see your program here, right click and delete file.

Do the same with HKEY LOCAL USER

Also go to start menu, search , type program name. When found, right click and delete all files.

optical drive not playing

This may not apply but it's worth a shot....

Click Start > Run
Type Regedit in the run box.

Look for keys called "Upper Filters" and "Lower Filters" and delete any values inside those keys, then restart the machine.

Note: If using Vista, be sure to right-click Regedit in the program list and choose "Run as Administrator", otherwise it won't let you change the values of the key.

Hope this helps,
