Technical Details


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.
