Do NOT use Norton Removal Tool in Vista system
Users who wish to remove Norton products using the Norton Removal Tool should NOT use it in Vista system.
Reason: It will damage/remove the Microsoft Tunnel Interface Driver (tunmp.sys) in Vista.
I reported it to Symantec so let's hope there will be an update on their Norton Removal Tool.
