旼컴컴컴컴컴컴컴컴컴컴컴컴컴컴� � VIRUS REPORT � � Saratoga Virus � 읕컴컴컴컴컴컴컴컴컴컴컴컴컴컴� Synonyms: 642, One in Two Date of Origin: July, 1989 Place of Origin: Calfornia Host Machine: PC compatibles. Host Files: Memory resident. Infects EXE files. Increase in Size of Infected Files: 642 bytes. Detected by: Scanv56+, F-Prot, IBM Scan. Removed by: CleanUp, Scan/D, F-Prot, or delete infected files. Derived from: Icelandic II? This virus appears to be derived from the Icelandic-II viruses. Modifications include: * When Saratoga copies itself to memory, it modifies the memory block so that it appears to belong to the operating system, thus preventing reuse of the block. * Like Icelandic-II, this virus can infect programs which have been marked Read-Only, though it does not restore the Read-Only attribute to the file afterwards. Similar to the Icelandic-II virus, the Saratoga can infect programs even if the system has installed an anti-viral TSR which "hooks" interrupt 21, such as FluShot+. �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.
