Removal

Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.

A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:

  • Check for the latest database updates

    First check if your F-Secure security program is using the latest updates, then try scanning the file again.

  • Submit a sample

    After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.

    Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.

  • Exclude a file from further scanning

    If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.

    Note: You need administrative rights to change the settings.

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.
