- Displays contextual advertising by injecting banner and text ads.


During setup, the program registers itself to launch on boot through a Windows Schedule Task in order to automatically start-up (this is typically done to avoid any UAC prompts). It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. It adds a Browser Helper Object (BHO) to Internet Explorer. A scheduled task is added to Windows Task Scheduler in order to launch the program at various scheduled times (the schedule varies depending on the version).

The software installer includes 7 files and is usually about 2.4 MB (2,513,227 bytes).
