Network Packet Analyzer or Online Ad Scanner are the names for the same potentially unwanted program, or PUP, that is installed by free software you download from the Internet. When installed, this program will configure itself to automatically start when you login to Windows. This constant downloading of web pages does nothing but slow down your computer and your Internet connection while providing no benefit to the user of the computer. The only way you would know it’s installed is that you may find it listed in the Uninstall Programs control panel or see the inetpc.
