W97M/Gamlet is a simple Word 97 macro virus.
Depending on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the suspect file, or ask you for a desired action.
More information on the scanning and removal options available in your F-Secure product can be found in the Help Center.
You may also refer to the Knowledge Base on the F-Secure Community site for more information.
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.
