Problems solved by technology

[0005] It is necessary to upload the file characteristics of all files that need to be scanned in the mobile terminal to the cloud server before cloud scanning can be performed. In the absence of free wireless network, it will consume a lot of traffic for users and cause users to generate a lot of traffic charges

Abstract

The invention provides a malicious application program scanning method, device and system and relates to the field of computers. The method includes connecting a PC terminal with a mobile terminal; acquiring the file characteristics of files to be scanned of the mobile terminal through the PC terminal; transmitting the file characteristics to a cloud searching and killing server to scan the malicious application program characteristics through the network transmitting capability of the PC terminal; receiving and outputting the scanning results returned by the cloud searching and killing server, and transmitting the scanning results to the mobile terminal. Since the connection of the PC terminal and mobile terminal is established, the file characteristics of the files to be scanned of the mobile terminal are acquired, the file characteristics are transmitted to the cloud searching and killing server to scan the malicious application program characteristics through the network transmitting capability of the PC terminal, the flow of the mobile terminal is not consumed when the files of the mobile terminal malicious application program are scanned in a cloud searching and killing manner, and the flow loss is avoided for users.

Description

technical field [0001] The invention relates to the field of computers, in particular to a scanning method, device and system for malicious application programs. Background technique [0002] At present, mobile terminals such as mobile phones and tablet computers are widely used. Android is a mobile terminal operating system based on an open source protocol. After years of development, it has become quite mature and can provide many functions. [0003] During the development of Android, there are more and more malicious programs targeting Android. At present, the method for identifying malicious programs is mainly by extracting file features of application programs, and then identifying them through a local antivirus engine. However, due to the limitation that the local virus database cannot take up too much storage space, and the virus database in the antivirus engine is usually not updated in time, the local detection and killing method does not have a high degree of rec...
