It is a very dangerous memory resident stealth boot virus. It hooks INT 9, 13h and writes itself to the MBR of the hard drive and the boot sector of the floppy disks. Depending on its counter that virus erases the sectors of the floppy disks. The virus intercepts warm reboot (Alt-Ctrl-Del) and tries to stay memory resident ever while loading from not infected disk. The virus contains the text strings:
I'm ASBV
No System!
