XM/Robocop is a simple Excel and Excel 97 macro virus.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
When an infected workbook is opened, the virus creates a new workbook, infects it and saves it to the Excel startup directory as "personal.xls".
After that the virus infects every workbook that is opened or created.
Beside replication, this virus contains a payload that activates on March 1st. At this time the virus modifies the formatting of the active worksheet and inserts the following text to it:
