W97M/Gamlet is a simple Word 97 macro virus.
Allow F-Secure Anti-Virus to disinfect the relevant files.
For more general information on disinfection, please see Removal Instructions.
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.
