I have an IBM ThinkPad T41, running windows XP sp2, Office Professional sp2, McAfee VirusScan 8.0 (updated with the latest definitions).
Here is what happens:
When I open any MSFT Office program, explorer.exe will jump to 90%+ (I installed SysInternals Process Explorer to follow the processes). After about 15 minutes explorer.exe will return to normal. I can then use the program like normal but if I open another Office program explorer.exe will return to 90%+.
If I close the Office program explorer.exe will return to normal.
If I kill the explorer.exe process and restart it and open any Office program explorer.exe functions normally.
I uninstalled and reinstalled Office and reapplied Office sp2. When any Office program is opened explorer.exe will again jump to 90%+.
Found no Spyware/Adware. Removed the indexing on hard drive as suggested in:
Found no Virus’ using Housecall and Stinger as suggested in:
And ran ccleaner 1.34.
