Embodiment Construction

[0024] The present invention includes computer program (software) and CDROM partition memory (hardware) with automatic operation function. Its core is an anti-infection method for removable memory viruses. A CDROM device with an automatic operation function that stores a specially written computer program is connected to a computer together with a removable memory, such as figure 2 , the specially written computer program includes running a main program, an injection program and an event processing program, running the main program to automatically run in the CDROM partition, running the main program to copy the injection program to a local temporary directory, and injecting the injection program into the operating system Kernel32.dll, replace the CreateProcessInternalW function of kernel32.dll with an alternative function injected into the program, to hijack the program operation mode of the computer system, and guide all running PE files to run through the event processing p...

Abstract

The invention discloses a method and a device for preventing viruses in a mobile memory from infecting a computer. A running main program, an injection program and an event processing program are set; and after the mobile memory is connected to the computer, the running main program automatically runs, and the injection program intercepts portable executable (PE) file program running modes of a computer system and guides all running PE files to run through the event processing program so as to control the running modes of all the PE files. The method and the device are used for preventing thepossible virus files in the mobile memory from infecting the computer and preventing the viruses from being diffused and propagated together with the mobile memory; a single machine runs in the method and the device, networking update is not needed, and full-automatic virus protection is realized for the mobile memory; and at least one mobile memory and the device are connected together with the computer, so the viruses in the mobile memory cannot infect/be propagated to the local computer or destroy the program of the invention no matter the viruses automatically run or are manually activated/opened/operated.

Description

technical field [0001] The invention belongs to the technical field of computers, relates to the protection of computer viruses, and relates to a method and a device for preventing viruses in removable storage from infecting computers. Background technique [0002] Removable memory has been widely used, and computer viruses are also widely spread through removable memory, causing huge losses. Existing virus protection technologies for removable devices include: [0003] [0004] [0005] To sum up, the virus protection technologies involving mobile devices mainly include: [0006] ①Install the signature code anti-virus software and HIPS anti-virus software for mobile devices in advance locally, or hijack local function security software, respectively, there are problems such as signature code anti-virus needs to be updated, lagging viruses and false interception, high missed interception rate, and inconvenient operation ; 2. The method of shielding the autoplay funct...
