You want to remove the Norman Security Suite software from your computer.
To remove Norman Security Suite from your computer you should run the included program “Delnvc5.exe” found in the “C:\Program Files\Norman\Npm\Bin” folder.
You can either navigate to that folder or press the “Win + R” and type in “delnvc5”.
When you have done that select Remove and press next. The software will then start removing itself.
After this has been completed you should reboot your computer when prompted, and when it’s back up delete the "C:\Program Files\Norman" folder.
