Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0037] The related technologies of the present invention are firstly explained below to facilitate the understanding of the present invention.
[0038] 1. The principle of mobile storage Trojan horse propagation:
[0039] There are two main transmission methods of mobile storage device Trojan horses: 1. Infection type, the poisoned computer infects the executable files in the mobile storage device, and the non-poisoned computer runs the mobile storage device, resulting in virus infection; 2. autorun.inf Driven, when the user double-clicks the mobile storage device, etc., the system automatically r...

The invention discloses a method and an apparatus for checking and killing Trojan of a removable storage device of a terminal. The method comprises the following steps of: activating the Trojan checking and killing program; judging whether the autorun configuration file exists or not; reading the content of the autorun configuration file of the removable storage device of the terminal to the buffer area of a memory distributed by the terminal; judging whether the content of the buffer area is empty or not; parsing the content of the buffer area, names and paths of Trojan; transferring the Trojan deleting program to delete the parsed Trojan program; and exiting the program. In the invention, the removable storage device can not be infected by Trojan by checking and killing Trojan in the removable storage device and parsing the autorun configuration file. The invention can be directly applied to mobile terminals to check and kill Trojan on the memory card without connecting the mobile terminals to the computer via a USB, which is convenient for users to operate.
Description
technical field [0001] The invention relates to communication equipment, in particular to a method and device for checking and killing Trojan horses in terminal mobile storage equipment. Background technique [0002] Most of the earlier terminal storage devices are fixed storage devices, such as hard disks, memory sticks, etc., which usually need to be fixedly installed in terminal devices (such as computers, mobile phones) and cannot be moved. However, with the development of technology, more mobile storage devices have been produced, such as floppy disks, mobile phone memory cards, flash drives (U disks), etc. These mobile storage devices have gained more and more popularity because of their portability and ease of use. more and more widely used. [0003] At the same time, due to the lag of security measures on terminal equipment, a large number of Trojan horse viruses have been produced. Criminals use Trojan horse viruses to steal user information for personal gain, whic...
