Has anyone else upgraded to Norton Antivirus 2005? I did and my whole system has slowed down appreciably, especially operations involving moving files. And Windows Explorer crashes whenever I open a directory with a large number of files. And I cant run a complete NAV system scan. I can scan individual directories, even entire drives, but it fails to finish a complete system scan. The system is WinXP Pro SP2. NAV is fully updated. Has anyone had NAV 2005 (or 2004) bog their system down or otherwise misbehave in this manner?
