Hate to say it, but Norton probably is the best. I like McAfee's interface much better, and I have had no trouble updating the DAT's or the engine in Windows 2000. However, Norton has optimized a little better for Windows 2000, and currently McAfee hasn't released a utility set that operates on Windows 2000 that I know of yet. <sigh> Guess it's Norton System Works for me.
