Windows Explorer keeps closing

[Guest]

I keep getting a message "Windows Explorer has encountered a problem and needs to close. We are sorry for the inconvenience." All day today, off and on, I get that message when trying to open documents or do other procedures.. I've also gotten it while trying to open Word 2000, Outlook Express 6 and Internet Explorer, with the name of the program in place of "Windows Explorer"

Sometimes the program work, and sometimes they don't.

Update your antivirus.
Download, install, and UPDATE the following programs:

Spybot-S&D (http://spybot.safer-networking.de/)
AND (it's AND, not OR)
Ad-aware (http://www.lavasoftusa.com/)

Disconnect Internet.
Restart computer in Safe Mode (see Help(F1) for more information), and
scan it using all these programs, antivirus first.

Update Windows.
