Technical Details


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.
