X97M/VCX is a Microsoft Excel 97 macro virus.
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:VCX.A
X97M/VCX.A activates when an infected workbook is closed or a worksheet is deactivated.
It creates a temporary file, "C:\Windows\System\Xlscan.386", and disables the macro virus protection via registry. Then the virus creates a new workbook, infects it and saves it to the Excel's startup directory with a name "Xlscan.xls". After that it infects every workbook using the temporary file.
It also creates eleven additional files to "C:\Windows\System" directory every time it gets control. Ten of these files will named after the current date and time, a number from 1 to 10 and the extension ".VCX"; while the last file will have a constant name "Xlscan.idx".
Variant:VCX.B
X97M/VCX.B is a slightly modified variant of X97M/VCX.A.
Variant:VCX.C
X97M/VCX.C is a modified variant of X97M/VCX.A. The file names are changed: Temporary file is "C:\Windows\System\MsOffice.386" and the file created to Excel's starup directory is "MsOffice.xls". Also the last file created to the Windows' System directory has a different name, "MsOffice.idx".
