Some versions of Adware.VirtualBouncer will display an End Use License Agreement (EULA) when they are installed, giving the software the right to download and install "updates" to the software from its servers.

Other versions may perform these actions silently, without telling the user what is happening.

Depending on the version, some of the following may happen:
  1. Creates the following files:

    • %ProgramFiles%\VBouncer\VBouncer.exe
    • %ProgramFiles%\VBouncer\VBDNR.dll
    • %AppData%\VBouncer\*.*
    • %UserPrograms%\Virtual Bouncer\*.lnk
    • %System%\vb2uninstaller4_19.EXE

      Note: %ProgramFiles% is a variable that refers to the Program Files folder. By default, this is C:\Program Files.
      %AppData% is a variable that refers to the following folder: C:\Documents and Settings\All Users\Application Data
      %UserPrograms% is a variable that refers to the following folder: C:\Documents and Settings\<current user>\Start Menu\Programs
      %System% is a variable that refers to the System folder. By default this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).

  2. Modifies the value:

    "VBouncer" = "C:\PROGRA~1\VBouncer\VBouncer.exe"

    in the registry subkey:

    HKEY_ALL_USERS\SOFTWARE\Microsoft\Windows\CurrentVerison\Run

    so that the adware will run on start-up.

  3. Creates the following registry subkeys:

    HKEY_CLASSES_ROOT\CLSID\{25AE1A9B-87D2-418F-A3A6-5A46EDC37A84}
    HKEY_CLASSES_ROOT\CLSID\{9CC6F6D3-8B13-4206-ABC1-8B285F9413A7}
