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

Variant:Cont.A

When an infected document is opened, W97M/Cont.A disables Word's built-in macro virus protection.

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 the virus changes the document summary information as follows:

 Title: Macro Carrier Subject: Dream Blaster Keywords: Minny

Every 17th day of each month, the virus checks for existence of "c:\minny.log" file. If the file does not exist, the virus appends several commands to the end of the "c:\autoexec.bat". These commands attempt to remove everything from "C:", "D:", "E:" and "F:" drives when the system is restarted.
