My university offers Norton Antivirus 9.0.2, but I want to switch over to the version of Virex that I downloaded from my .Mac account. The Virex refuses to install citing that I have other antivirus accounts causing issues. I have deleted all Norton and Live update files and I am sitll having issues. I am not sure if I have problems with the uninstallation or with the Virex installation. Has anyone else had these troubles?
