When Adware.EZSearch runs, it does the following:

  1. Creates the following file:

    %SYSTEM%\ezs.dll

    Note: %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. Creates the following registry keys:

    HKEY_CURRENT_USER\Software\eeee
    HKEY_CLASSES_ROOT\eeeezzzz.CSrcBnd.1
    HKEY_CLASSES_ROOT\eeeezzzz.HBO.1
    HKEY_CLASSES_ROOT\eeeezzzz.HBO
    HKEY_CLASSES_ROOT\eeeezzzz.Inst.1
    HKEY_CLASSES_ROOT\eeeezzzz.Inst
    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\EZ

    HKEY_CLASSES_ROOT\INTERFACE\{944F4137-C25C-41BD-ABA7-554FAAA59F56}

  3. Modifies the Hosts file (located at %SYSTEM%\drivers\etc\hosts in Windows XP and 2K and %Windir%\hosts in Windows 98/ME) by adding the line:

    64.159.94.251 auto.search.msn.com

    which redirects searches to ezcybersearch's search site.

    Note: %Windir% is a variable that refers to the Windows installation folder. By default, this is C:\Windows or C:\Winnt.
