We have a computer running Win 98 SE and using Office 2000 Pro. We have had no problems so far. All of a sudden (last week), the computer could not open any office documents. Upon searching, we discovered that office was not on the computer - it had been mysteriously removed. We re-installed Office and all was fine (Friday). This morning, they turned the computer on and could not access any office documents. Once again, it looks as if Office was uninstalled. Can anyone give any insight to this problem - is it a virus - has anyone ever heard of this?? "Try everything at least once."
