XM/Neg is an Excel macro virus. When an infected workbook is opened, the virus first removes several menus from the Excel.
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.
Then it creates an infected workbook, "DOLLAR.XLM", to the Excel startup directory. After that every workbook that is opened with Excel will be infected.
The virus activates its payload if the infected workbook is closed on the 13th day of any month. On this date it appends a small code to the "C:\AUTOEXEC.BAT" file. On the next restart, this code will delete all "*.com", "*.vxd", "*.drv" and "*.dll" files from the Windows directory "C:\WINDOWS". The payload does not work in Windows NT. Then the virus shows a message box with the following text:
