Did this CD come with anyone's machine? It was installed on my machine but I keep getting an error - "Norton Antivirus does not support the repair feature, please uninstall and reinstall". It is very annoying becuase it does this everytime you open a document and pops up 2-3 times. I want to try to use Norton as I've been finding the McAfee just sucks up too much system resources for my liking. Why have anti-virus that slows your machine down so much, its almost worse than having a virus.
