On installation it hits COMMAND.COM and DOSFORMAT.COM files, then it hooks INT 21h and writes itself at the end of COM- and EXE-files that are accessed. It contains a bug, as the result in some cases infected files halt PC on execution. It contains the internal text strings:
COMMAND.COM DOSFORMAT.COM
ZIPPER.ASM

Description not-virus:Joke.Win32.FakeFormat.a

Fake Format simulates the Windows format functionality.
Once the program is run, no matter which buttons are chosen, Fake Format starts to format the drive. The user is unable to stop, interrupt, or cancel this format. Once the fake formatting has been completed, the standard Windows format summary appears. Once the user has closed this summary screen, the button actually closes the program.

not-virus:Joke.Win32.JepRuss

Description not-virus:Joke.Win32.JepRuss
Jep/Russ is a joke program - it is not a virus or a Trojan program. It displays too scaring messages that can really frighten users. When this program launches it displays a standard message window with the text:
Please Wait. Initialisingall

In a moment it displays a dialog box with the following text:
Confirm Folder Delete
Are you sure you want to delete the folder [Windows] and all its contents ?
[Yes] [No]

The '[Windows]' reference designates the directory where Windows is installed. Regardless of a user's reaction, including sitting motionless afraid to touch any key, the program then displays the standard Explorer and 'File Deleting' windows and proceeds to emulate the file and folder deletion process. When the fake display indicates 'no files remaining', 'Jeb/Russ' displays the standard Windows shut-down menu with disabled (gray) [No] button and the following text:
Shut Down Windows
Windows has detected there is no system software on your computer

(*) Shut down the computer?
( ) Restart the computer?
( ) Close all programs and log on as a different user?

[Yes] [No] [Cancel]

The below message is then displayed:
Thank god this is only a game...

Note: The detection process for this joke program has been added to AVP database.
