Malware type VIRUS
Spreading mechanism FILE_INFECTION
Summary None



X97M/Barisada.A is a small virus. The virus will spread on closing of the spreadsheet. It will check if the file HJB.XLS already exists in the Excel Startup directory. If not, it will drop this infected template there. The next time Excel is loaded, it will automatically load this infected file as well. The next action is to infect all modules and worksheets in all loaded spreadsheets.
