Technical Details

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.
