W97M/FF is a simple Word class infector.
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.
Variant:FF.AMacro.Word97.Lys.i
When an infected document is opened, W97M/FF.A deletes the "Tools/Macros" menu and disables the built-in macro virus protection first. Then the virus creates a temporary file, "C:\FF.sys", and infects the global template.
Afterwards every opened document is infected.
the virus activates its payload on the first day of every month. It alters the "c:\msdos.sys" file by changing the
BootGUI=1
line to
BootGUI=0
This causes Windows 95/98 to start in command line mode after boot, instead of graphical user interface (GUI).
Variant:FF.C
This variant is functionally identical with W97M/FF.A.
