- │ Jerusalem-C │
- └─────────────────────────────┘
-
- Synonyms: the New Jerusalem.
-
- Date of Origin: October 14, 1989.
-
- Place of Origin: first reported in the Netherlands by Fidonet SYSOPS Jan
- Terpstra and Ernst Raedecker. May have originated elsewhere in Europe.
-
- Host Machine: PC compatibles.
-
- Host Files: Remains resident. Infects COM, EXE, SYS, BIN, PIF, overlay
- files.
-
- Increase in Size of Infected Files: 1808 bytes (EXE), 1813 bytes (COM).
-
- Nature of Damage: Affects system run-time operation. Corrupts program or
- overlay files.
-
- Detected by: Scanv45+, F-Prot.
-
- Removed by: CleanUp, Saturday, F-Prot.
-
- Derived from: Jerusalem-B.
-
- This virus seems to be a special version designed to elude virus
- detectors, including McAfee's Scan versions prior to 45 and IBM's
- VIRSCAN of October 20, 1989 and earlier.
-
- This virus is identical to Jerusalem-B except that the timer
- interrupt delay code has been bypassed. That is, it will not slow your
- computer when it has activated. This virus is virtually invisible until
- it activates. It infects both .EXE and .COM files and activates on any
- Friday the 13th, deleting infected programs when you attempt to run
- them. This virus is memory resident, and as with the other Jerusalem
- viruses, may infect overlay, .SYS, .BIN, and .PIF files.
