Abstract: A method and a user device for processing virus files. First information of at least one category of virus files and second information of a manner for processing each of the at least one category of virus files are provided. A category of a virus file when the virus file is identified. A manner of processing viruses of the category from the first information and the second information is obtained and the virus file is processed by using the manner without information about the virus file being presented to a user.

Abstract: A method for bandwidth optimization of network application is disclosed. The method includes the steps of: classifying and identifying running network applications according to a set profile, and obtaining network applications of a first category; estimating the bandwidth of the running network applications, and obtaining an available bandwidth of network applications of the first category; obtaining bandwidth occupied by network applications of the first category, and determining whether the bandwidth occupied by network applications of the first category is higher than the available bandwidth; and if yes, then adjusting the bandwidth occupied by network applications of the first category. By the above method, system and computer-readable storage medium for bandwidth optimization, the possibility of network congestion is reduced, and the network fluency of the network applications of the system is improved.

Abstract: According to an example, a client device determines at least one virus sample according to at least one anti-virus engine, transmits sample information of the at least one virus sample to a server, such that the server determines a first virus sample set needs to be reported according to the sample information of the at least one virus sample and a predefined sample information list in the server, and returns to the first virus sample set to the client device. The client device receives the first virus sample set needs to be reported and performs a virus reporting operation according to the virus sample set.

Abstract: Apparatus and method for preventing payment page tampering are described herein that determine whether a request received by a webpage modification interface is an inter-process request made by another process different from a process running the webpage modification interface and that, in response to determining that the first request is an external request, intercepts the first request. Embodiments of the apparatus and method can improve security of Internet payment transactions.
