I have unistalled Norton 360 and installed Norton Internet Security 2009 because of an error message in Mediacenter related to SymAddin component I have removed all SymAddin entry key from the system registry...I have damaged a component of Norton Internet Security 2009 or SymAddin entry-key was a residual of Norton 360 installation?
What is SymAddin component? Is present in Norton Internet Security 2009? Sorry for my bad English, I'm Italian.
