It is possible that, when you ran your anti-malware software, it deleted / moved / renamed the Winword.exe file due to an infection.
One suggestion I can offer is to try looking into your anti-malware program(s) and see if you can restore any previous winword.exe files. If you can't then the only thing I can think of is to do a repair install of Office 97.
However someone else here may have a better solution than me, so you should probably wait for some better answers ;)
