- 1) Infecting (SMIT) MEMCHECK.EXE
- --------------------------------
- D:\A_VIRUS\ARC>go_en1 memcheck.exe /SMIT
- Checking for virus / <-- A_Virus internal virus check
- D:\A_VIRUS\ARC>
- NOUPDOWN
- The program MEMCHECK.EXE was infected with the friendly A_Virus, GO_EN1
-
- ---
-
- Running the infected program MEMCHECK.EXE, gives this result:
- D:\A_VIRUS\ARC>memcheck
- Checking for virus / <-- A_Virus internal virus check

- D:\A_VIRUS\ARC>go_en1 memchck2 /SMIT <-- ERROR: extension EXE is missing

- GO_EN1 (A_Virus Anti Virus Software Tester).
- Created for EDLAB AntiVirus Division for test purpose.
- Copyright (C) 1993 Karlius, Dan and Guns.
-
- Usage:
- GO_EN1 exe_file /SMIT
-
- P.S.: When exe_file is infected with A_Virus the following parameters
- can be used:
-
- exe_file /FJERN to remove A_Virus.
- exe_file /GRAFIK to show a graphic A_Virus.
- exe_file /INFO to show this information.
-
- D:\A_VIRUS\ARC>

- Well, that was not possible. Extension EXE was missing.
-
- GO_EN1 presented the USAGE message. This is done when /SMIT fails and
- at other error occasions.

-
- MEMCHECK.EXE was supplied in its NON protected version, MEMCHECK.EXE and
- its protected version MEMCHK2.EXE.
-
- MEMCHK2.EXE is protected with EMBEDDED EDLAB-Vaccine.
- EDLAB-Vaccine protects against Patch Professors and Virus attack.

- Testing MEMCHK2.EXE:
- --------------------
-
- 1) Infecting (SMIT) MEMCHECK.EXE
- --------------------------------
- D:\A_VIRUS\ARC>go_en1 memchk2.exe /SMIT
- Checking for virus /
- D:\A_VIRUS\ARC>
-
- Well, that worked well for the friendly coupler virus GO_EN1. MEMCHK2.EXE
- was successfully infected.
-

-
- Now let us see what happens, when we RUN MEMCHK2.EXE after infection:

- First the viral code was run. Nobody can avoid that, but then:

-
- EDLAB_Vaccine successfully identified the A_Virus AND stopped the program.
- Do NOT run a virus infected program (In this case it is OK, as GO_EN1
- is a friendly A_Virus).
-
- Only a virus free backup can restore an attacked program.
-
- As the virus is the friendly A_Virus, GO_EN1, nothing sinister happened.
-
- *: I think this little test give you some impression of the danger the
- PC Virus is.

-
- EDLAB_Vaccine protects against more than just viruses. Patching is not
- possible, when EDLAB-Vaccine is embedded.
-
- Note: MEMCHECK.EXE is NOT protected.
-
- Make a copy of MEMCHK2.EXO to MEMCHK2.EXE and patch a text in the program.
- (NO, you cannot easily patch the code, if you want the program to be
- functional).
-
- This is what happens if you patch an EDLAB-Protected program. Incidentally,
- ALL EDLAB programs are protected, also our shareware programs. We want you
- to have healthy programs.
