My computer orignally had Norton Antivirus 2002 installed. I have purchase McAfee software for the past several years and every year I have trouble installing because it initially detects the Norton Software, even though it was uninstalled initially. Last year the forum gave me help in removing a Norton reference in the registry and I was able to install the McAfee software. But again, this year, when I purhcased McAfee Internet Secuirity 2009, it again said that Norton Antivirus 2002 was installed. I would appreciate any help you can give me!
