My desktop (with XP and Firefox Yahoo edition) frequently stalls. And when I go to Task Manager/Processes I see that my CPU is running at 100%. The major user is “Winword.exe” at 75-88%. So far as I know I never activated Winword.

a. What might have caused all that CPU consumption?
b. Is it safe (despite the MS warning) to right-click and delete WinWord.exe?
c. Is there some fix I should be making to avoid these situations?

Thanks. ...wdc
