It searches for .COM files of the current directory and writes itself to the end of the file. The code that passes the control to virus body consists of two parts: the first part (the file beginning) jumps to the second one, and the second jumps to the main virus body.

Sometimes it also searches for .EXE files and overwrites them with a trojan program that erases the disk sectors and display the messages: ������������ �������������� � __ __ � � o o � � � � (..) � � ) ---- ( � __________/ The User of This Computer Is Stupid!
