   ---

   Note: %System% is a variable. By default, this is C:WindowsSystem (Windows 95/98/Me), C:WinntSystem32 (Windows NT/2000), or C:WindowsSystem32 (Windows XP).

2. Adds the value:
   
   "svrhost" = "%System%Svrhost.exe"
   
   or
   
   "msstart" = "%System%Msstart.exe"
   
   to the registry key:
   
   HKEY_LOCAL_MACHINESoftwareMicrosoftWindowsCurrentVersionRun
   
   so that the adware runs when you start Windows.
   
   
3. Adds the values:
   
   "SM_AccessoriesName" = "Accessories"
   "SM_GamesData" = "<random value>"
   "SM_GamesSetup" = "0"
   
   to the registry key:
