Nortorn interner security 2006 uninstall
You have to pull it out by the roots, literally, .
Go into a DOS shell and find the directory and wipe it clean.
You may have to use some ancient dos commands to make some of the parts visible, like ATTRIB
You may have to ATTRIB +R +S +A +H (Read System Archive Hidden) to make your deletions work.
Now, I have not exactly spelled out how this works, intentionally, in the event that if you don't feel comfortable working at DOS level with line commands, you should turn the work over physically to someone who does feel comfortable. If you understood what I wrote above then go ahead and DIY!
