I tried to upgrade my Norton Antivirus, but it turns out it's not compatable with Windows 2000 that I use. I worked with a tech on this and he finally deicded that was the problem so I got a refund on my subscription. Now I'm wondering if I can just delete the file I downloaded, which is in my Downloads file, put there by Firefox. There are also two Norton folders in C:\Program Files - Norton Antivirus (which has a 7/14/08 date on the folder, and NortonInstaller, dated 6/25/10. I don't see these programs in Windows uninstaller, so I'm wondering how to get rid of them. The folders are not empty.
