WM/Verm is a macro virus that infects Word documents.
When an infected document is opened, the virus will gets control and infects the Word's "NORMAL.DOT" template. After that, the virus infects every document while it is closed.
This virus has a destructive payload which activates when any infected document has been opened three times. Then it deletes all files from the Word's graphic filters, text converters, proofing tools and style gallery templates directories.
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.
