Upon installation and setup, it defines an auto-start registry entry which makes this program run on each Windows boot for all user logins. It adds a background controller service that is set to automatically run. Delaying the start of this service is possible through the service manager. The program adds a toolbar to Microsoft 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 is designed to connect to the Internet and adds a Windows Firewall exception in order to do so without being interfered with. The main program executable is np-mswmp.dll. The software installer includes 571 files and is usually about 909 KB (930,816 bytes). gfwlupdate.dll is the automatic update component of the software designed to download and apply new updates should new versions be released.
