The length of the virus is either 1232 (COM) or 1472 (EXE) bytes, depending on the file type.
The virus will activate when it has been in memory for 30 minutes. After that it will start interfering with the keyboard, by occasionally repeating the pressed key several times.
Keypress may also display the string "OOOOOOOOOOOOOOOO" on the screen, and emit beeps from the system speaker.
There are several variants of this virus, some of which seem to have been written in USA, Australia and Singapore.
