Trouble:
Some viruses corrupt the Norton Anti-virus itself sometimes, so much so that the anti-virus stops working, and you can not uninstall Norton Anti-virus.

Fix:
As we said, the fix is really simple, there is a tool developed by Symentec only that will help remove Norton products in case it gets corrupted due to any reasons.

Its called Norton removal tool, a small exe program (about 650 KB) . Before running this program make sure that you save your product key for installing the anti-virus later. Download the tool from the link at the bottom of this post.

The Norton Removal Tool uninstalls all Norton 2008/2007/2006/2005/2004/2003 products and Norton 360 .

Also one more warning from Symantec is: If you use ACT! or WinFAX, back up those databases before you proceed.
