Summary

This is a very small but dangerous DOS-based trojan program. When run it analyses the command line and if a valid drive and directory is found it deletes the specified directory and all its subdirectories. Files with all attributes are deleted in attacked folder.

If no command line is specified the trojan outputs a message: "Requires more memory to run"

If path specified in command line is not found the trojan outputs: "Out of memory error. Please reboot"

If a trojan fails to delete any file (for example shared Windows file) in attacked folder it outputs: "Could not attack " and a file name. After the first failure the trojan exits to system (and this saves the rest of data).

If the trojan is run with "C:\" command line it will wipe most of data on the disk in a few seconds.
