WM/Setmd is a simple macro virus that activates when an infected document is opened in Word. It infects the global template and all opened documents thereafter.
It also sets a timer so the virus attempts to infect the active document in every five minutes.
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.
