Norton Internet Security & Norton Antivirus 2002 run just fine. It may seem obvious, but you really need to update the Norton products when you update your operating system. I've sworn by Norton since I bought Windows 95. I used to hate them in the DOS/Windows 3.1 days... I loved Central Point's PC Tools. But Symantec bought them out, killed the product. They surprised me by coming out with some great products.
