Maybe this . http://langa.com/newsletters/2004/2004-01-15.htm A *very* weird chain of events affected huge numbers of users of Microsoft Office and Norton Antivirus last week--- and may still be affecting some. Other users were affected too, although in lower numbers. You'll know if you're effected because your copy of Microsoft Word became very, very slow to open; and Excel might not have been able to start at all; and/or your whole system may have bogged down. The problem isn't in Word, Excel, Windows, or NAV--- but is something else entirely: But there's a fix on both the Symantec site, above, and at Verisign ( http://langa.com/u/2t.htm ). If your PC is still slow or erratic, check out those links.
