When Adware.Fastwebfinder is executed, it does one of the following:


Adware.Fastwebfinder is not yet installed in %Windir% folder
If Adware.Fastwebfinder does not find the file %Windir%\Ld.exe, it will do the following:
  1. Copies itself as %Windir%\Ld.exe.


    Note: %Windir% is a variable. The adware locates the Windows installation folder (by default, this is C:\Windows or C:\Winnt) and copies itself to that location.

  2. Adds the value:

    "Ld"="%windir%\ld.exe"

    to the registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

    so that the adware runs each time you start Windows.

Adware.Fastwebfinder is already installed in the %Windir% folder
If Adware.Fastwebfinder finds the file %Windir%\Ld.exe, it will do the following:
  1. Connects to www.fastwebfinder.com.
  2. Downloads information, including the file Dnse.dll, which it copies to the %Windir% folder.
