旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴� � VIRUS REPORT � � Black Hole � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴� Synonyms: the Russian Virus. Host Machine: PC compatibles. Derived from: Jerusalem-C This virus is the Jerusalem-C that has odd text and additional code that is never referenced. A new interrupt eight routine is added to the non-referenced area and a number of interrupt 21 calls which appear meaningless. The additional text includes "ANTIVIRUS". It appears that this virus is a modified version of the Jerusalem-C/New Jerusalem. Note that because of the difference in EGA and CGA int 10 usage, Jerusalem A has been observed with the blackhole effect noted on an EGA screen. �袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴袴� � This document was adapted from the book "Computer Viruses", � � which is copyright and distributed by the National Computer � � Security Association.
