X97M.Barisada.O is a macro virus that infects Microsoft Excel spreadsheets. On infected systems, X97M.Barisada.O replicates by copying itself, line by line, to Microsoft Excel spreadsheets when they are opened. By inserting a file into the Excel startup folder (usually \Xlstart), the virus ensures that it will be executed every time that Microsoft Excel is started. The virus has a payload that triggers on the 25th of every month.
