When the virus is loaded into memory, it hooks INT 16h, 21h and infects any executable that is run by a standard manner. The virus may remove itself from the infected files in some cases.
The infection size varies in different files.
The exact memory usage is 12,304 bytes.
Once the virus activated, the payload from Abraxas.1214 was loaded (which contains an indecent ASCII image that says "Sara's Groove" along with a sound from Burma.756 payload) and afterwards, the virus displays a moving man from a DOS port of Bad Street Brawler by Beam Software Pty., Ltd in every 30 seconds approximately, at this moment all inputs by the user would not be reflected onto the screen until the man is left.
If the user loaded a graphical program when the virus is in memory, it would hang the system.
This virus contains the internal text string:
