It also creates the following registry entries:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Wajam\"DisplayName" = "Wajam"
  • HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Wajam\"DisplayIcon" = "%ProgramFiles%\Wajam\Logos\wajam.ico"

Next, the application creates a service with the following properties:
  • Display Name: Wajam Internet Enhancer Service
  • Image Path: "%ProgramFiles%\Wajam\Wajam Internet Enhancer\WajamInternetEnhancerService.exe

The program then creates the following registry subkeys to register itself as a service:
  • HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\services\Wajam Internet Enhancer Service
  • HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Wajam Internet Enhancer Service

The application then launches the default Web browser and requests the user to log in to Wajam using their Facebook or Twitter credentials.

If the user does not log in to Wajam, the application may inject a login form into a number of well-known websites.
    If Facebook or Twitter credentials are used to login, the application asks for permission to access the user's posts.

    The application will display posts from the user's social media contacts whenever a search is carried out on one of the websites.

    The application may also display advertisements related to searched keywords.

    Advertisements are displayed even if the feature is turned off in the application's setting page.
