W97M/Arbeit is a Word 97 macro virus with a destructive payload.
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 detection database 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.
When an infected document is opened, W97M/Arbeit.A disables the built-in macro virus protection, the status bar and the following menus: "Tools/Macros/Macro" and "Tools/Macros/Visual Basic Editor". It also modifies the user name and initials to:
User name: NoWork Inc. Initials: NWI
Then the virus creates a temporary file "C:\mlpog.sys" that it uses to infect the global template and all documents closed after that.
The virus activates its payload every day after October 15th, when it shows a message box with the following text:
The technology will be kill humaneness
After the message box has been shown, it deletes all files from the root directory of the "C:" drive.
