F-Secure Virus Descriptions : Eddie 2





NAME:Eddie 2
ORIGIN:Bulgaria
SIZE:651
TYPE:Resident COM/EXE-files
REPAIR:Yes

A fairly harmless virus from Bulgaria - called "Eddie II" because it contains the string "Eddie lives". This string is similar to the string contained in the original "Eddie" virus. Eddie II can infect .EXE files as well as .COM files, but unlike most other .EXE infecting viruses, it does not pad them so their length becomes a multiple of 16 bytes, before they are infected. Infected files are marked with a value of 62 in the "seconds" field of the timestamp, which makes them immune to infection by Vienna or Zero Bug. Infected files grow by 651 bytes, but this increase will not be seen if a "DIR" command is given, because the virus intercepts the "find-first" and "find-next" functions, and if the "seconds" field contains 62, the virus will decrement the file length by 651. Apart from this the virus does nothing of interest.
