W97M/Gamlet is a simple Word 97 macro virus.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
When an infected document is closed, the virus shows the following message in the Word's status bar:
TO BE OR NOT TO BE ?...
Then it infects the global template and every document that is closed thereafter.
It also disables the Word's built-in macro virus protection when Word is restarted and hooks "Tools/Macros/Macro" dialog rendering it unusable.
