It's a harmless memory resident boot stealth virus. It copies itself into the Interrupt Vectors Table, hooks INT 13h and writes itself into MBR of hard drive and boot sectors of floppy disks. It contains the internal text string:
SEA.Moscow.5-29-1992.I think, it is a smallest stealth virus.It occupies
memory 002D3-00339.It workes with 1.2M diskette as good as with 360K.It is
harmless and do nothing(if you don't use BASIC).You can remove it with
overwriting (even in ill computer).Good bye!
