Summary



W97M/Reiz is a destructive Word trojan.

When a trojan document is opened, it creates a batch file, "Autoexek.bat", and an AutoRun file to the root of the "C:" drive.

When Windows is restarted, the AutoRun is enabled and when the "C:" drive is accessed via Windows Explorer or My Computer the batch file is executed.

The batch file shows a message:

  Updating! This May Take A While...
    Please Wait...

and then attempts to remove everything from the "C:" drive using "Deltree" command.
