ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿ ³ VIRUS REPORT ³ ³ Saratoga Virus ³ ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ 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+.
