100% cpu... explorer.exe is using 99% of it

[Guest]

Last week we noticed that Outlook, Word, etc. were taking a very, very long
lime
to come up. I checked Task Manager and the cpu is at 100% w/ explorer.exe
using 99% almost all the time.

On Friday I was cutting and pasting from one document to another when I got
an error msg saying explorer.exe had a fatal error and would be closing.
When I clicked ok the cpu dropped from 100% back down to a normal level. I
haven't been able to recreate this again. At least it would give me a
workaround until I could figure out what is going on. Any ideas?

1. we have macaffee anti virus and update it as soon as there's a change
2. we run scans every few days
3. we also run spybot
4. scans have shown no viruses, no adaware, no spyware, no malware
5. we are up to date on all windows updates

Could it be a corrupted file that's causing explorer.exe to hang? If it is,
how do I figure out which file it is?

Thanks in advance for your help.

Download MULTI_AV.EXE from the URL --
http://www.ik-cs.com/programs/virtools/Multi_AV.exe

To use this utility, perform the following...
Execute; Multi_AV.exe { Note: You must use the default folder C:\AV-CLS }
Choose; Unzip
Choose; Close

Execute; C:\AV-CLS\StartMenu.BAT
{ or Double-click on 'Start Menu' in C:\AV-CLS }

NOTE: You may have to disable your software FireWall or allow WGET.EXE to go through your
FireWall to allow it to download the needed AV vendor related files.

C:\AV-CLS\StartMenu.BAT -- { or Double-click on 'Start Menu' in C:\AV-CLS}
This will bring up the initial menu of choices and should be executed in Normal Mode.
This way all the components can be downloaded from each AV vendor's web site.
The choices are; Sophos, Trend, McAfee, Kaspersky, Exit this menu and Reboot the PC.

You can choose to go to each menu item and just download the needed files or you can
download the files and perform a scan in Normal Mode. Once you have downloaded the files
needed for each scanner you want to use, you should reboot the PC into Safe Mode [F8 key
during boot] and re-run the menu again and choose which scanner you want to run in Safe
Mode. It is suggested to run the scanners in both Safe Mode and Normal Mode.

When the menu is displayed hitting 'H' or 'h' will bring up a more comprehensive PDF help
file. http://www.ik-cs.com/multi-av.htm
