When Adware.HungryHands is executed, it does the following:
  1. Copies itself to the %Windir% or %System% folder as one of the following:
    • hh.dll
    • hu.dll
    • hhu.dll


      Notes:
    • %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.
    • %System% is a variable. The adware locates the System folder and copies itself to that location. By default, this is C:\Windows\System (Windows 95/98/Me), C:\Winnt\System32 (Windows NT/2000), or C:\Windows\System32 (Windows XP).
