W97M/Akuma is a Word 97 class infector. It contains a destructive payload.
When an infected document is opened, W97M/Akuma.A disables Word's built-in macro virus protection.
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 the document is closed, it infects the global template. During infection the virus creates a temporary file, "c:\cont.dbl", and deletes it afterwards.
At random times this virus changes the document summary information as follows:
Title: Akuma Macro Carrier Subject: Akuma Keywords: Mary Bitch
Between every 16th and 18th day of each month, the virus checks for existence of "c:\mary.log" file. If the file does not exist, it replaces every recently opened document (listed in the "File" menu) with the following text:
Something wonderful has happened, your PC is alive and even better but some of your documents are infected by the Akuma virus. Mary is simply a bitch and you, (Username), are a stupid jerk and lose some files. Have a nice day.
In the above text "(Username)" has been replaced with the current user name.
The original content of these files is lost.
