90% of my icons open Nero

hi, somehow i accidently made it so that all my programs open with Nero Back It Up 2, so when i try to open things like WoW, Itunes, AVG, and RealPlayer they all open up Nero backitup insted of there program, is there any way to fix this?

It sounds as though Nero captured your system!

Uninstall Nero. Then run the Nero Clean Tool.

See if all reverts to normal.

When you reinstall Nero be sure to deselect everything when you come to the Nero default associations.
