ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿ ³ VIRUS REPORT ³ ³ Suriv03 ³ ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ Synonyms: Israeli, Suriv 3.00 Place of Origin: Israel. Host Machine: PC compatibles.

Increase in Size of Infected Files: 1813 bytes (COM files) and 1808 bytes (EXE files). Nature of Damage: Affects system run-time operation. Corrupts program or overlay files. Detected by: Scanv56+, F-Prot, Pro-Scan. Removed by: CleanUp, Scan/D, F-Prot, or UnVirus. Derived from: Suriv02. Scan Code: You can search at offset 099H for FC B4 E0 CD 21 80 FC E0 73 16. This virus is nearly identical to the Jerusalem virus, which is much better known, and which was derived from it. The virus activates on Friday the 13 when an infected program is run. It does not delete files, due to a bug in its code. On other days, after the virus is memory resident for 30 seconds, an area of the screen is turned into a "black window" and a time wasting loop is executed. Differences from the Jerusalem virus: * the string "sUMsDos" found in the Jerusalem is "sURIV 3.00" in this version. * the 30 minute delay (before machine slow-down) in the Jerusalem is 30 seconds in this version (making detection easier with this virus than with the Jerusalem); * there is a bug in the program delete function of the virus, making this version less lethal than the Jerusalem.
