It is a dangerous memory resident boot virus. It hooks INT 9, 13h and writes itself to the boot sector of floppy disks on reading from them. It infects the hard drive while loading from infected floppy. It saves the original MBR sector on the 7th hard drive sector and the original boot sector on the last root directory sector of a diskette. Because of an error while infecting floppy disks the virus corrupts the disk parameters table.
On entering keys (INT 9) the virus changes the color attribute of top-left character on the screen.
