Alert Type: Initial Infection Spread
Library Entry: Joshi-B
Entry Type: Boot Sector & Partition Table / "Stealth" Virus

	The Joshi virus has been reported and verified on July 30 on
a number of workstations in a local area network in North Carolina,
marking the first incident of the virus reported to the CVIA in the
South-Central U.S.  A variant of Joshi was also reported and
verified on July 31 in Riyadh, Saudi Arabia.  It has been named the
Joshi-B.  This variant causes destruction of the Partition Record
and boot sector of hard disks, as well as the virus' normal
interference with floppy diskette use.
	The virus is a "stealth" Boot sector and Partition Table virus
and thus is very difficult to identify on an already infected
system.  It is becoming widely dispersed in the U.S. and is likely
to become one of the more common viruses, based on its past
performance and speed of replication.
	A remover for the virus is available through your CVIA contact
person.
