This is a harmless memory resident parasitic virus. It hooks INT 21h and infects COM and EXE files. On April, 22th (Vladimir Lenin birthday) it jokes with the screen - it writes random data to the video ports, and the screen starts to twitch and grimace. Under the Windows the screen do not twitch but the vertical and horizontal borders of active window are changed every second.
