X97M/Clonar is a simple 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:Clonar.A
When an infected workbook is opened, X97M/Clonar.A disables both "Tools/Macros/Macro" and "Tools/Macros/Visual Basic Editor" menus.
Then the virus creates an temporary file, "C:\Windows\Diablos.bas", and it uses this file to infect all open workbooks.
Every 30th day of each month the virus activates its payload. At this time X97M/Clonar.A changes the size of toolbar buttons to large.
