I’ll be saying more about the Registry later.
First thing to do is Back up the Registry. The next step is trickier: go into the Registry. Repeat step 5 except type Symantec in the “Search” box. Now type in Norton and delete each Norton folder from the search results (Again, right click, choose Check each option except for “Case sensitive” Go to Start –> Search –> All Files and Folders –> More Advanced Options. While you are in Program Files go to the Common Files folder at or near the top of the Program Files window. Right click on each Symantec folder and select Delete.
Now go to Start –> My Computer –> Program Files.
Go to Start –> Control Panel –> Add/Remove Programs. Generally, you remove applications by using the Windows utility for the task, but Norton Antivirus tends to get in a bit deeper into the system, so it’s tricker to remove it completely.
