In the information age,mobile Internet application technology has brought people a lot of convenience, but often difficult to detect hidden“traps”,application bundled download is one of them. According to some investigations, the current bundled downloading behavior in the Internet application market is still widespread, and existing departmental regulations are difficult to be effective. After clarifying the legal subject of application providers and network users in the B2C model under the context of the Law of the People’s Republic of China on the Protection of Consumer Rights and Interests, the facts are confirmed that this behavior infringes on the rights of the network users as consumers, such as their right to know and choose. Therefore, it is possible to reoulate the behavior ofnternet companies and protect the riohts and interests of Internet users according to the Law on Protection of Consumer Rights and Interests. So it is necessary to change the formal examination to substantive examination in the procedure that the applications go online, to set up a supervision team and innovate the model of industry self-discipline manage ment, to strengthen the popular law education and improve public awareness of rights protection to ensure that bundled downloads of application are eliminated. Only in this way, can the Internet application market thrive on the premise of orderly and healthy development.
