The application relates to the field of microorganism detection, in particular to a respiratory virus rapid detection kit based on ZIF-8 material and a preparation method, wherein the kit comprises a virus collecting device, an exhalation cylinder and a ZIF-8 membrane, the ZIF-8 membrane is detachably arranged in the exhalation cylinder, the ZIF-8 membrane comprises a chitosan layer, the chitosan layer is uniformly distributed with ZIF-8 material, virus particles in the exhaled gas of a tester through the exhalation cylinder are adsorbed, a sample processing device comprises a processing liquid, the processing liquid elutes and lyses the virus particles adsorbed by the ZIF-8 material distributed on the chitosan layer, and a virus processing liquid is obtained, a detection reagent is used for detecting the virus processing liquid and giving a detection result, sampling is simple and rapid, the detection can be completed without the participation of professionals, sampling efficiency is higher, and the detection sensitivity is effectively improved.

The application discloses a virus searching and killing method and system for distributed energy safety data, relates to the field of virus processing, and comprises the following steps: acquiring a virus original characteristic code, splitting the original characteristic code into N discontinuous but sequentially fixed segments F i , calculating the starting offset S i of each segment F i relative to the first segment F1, and constructing a virus characteristic database; then, the data stream is divided into multiple data blocks B i of fixed size, a fixed-size sliding window is adopted to perform scanning and matching association, and finally, threshold judgment is performed; the original virus characteristic code is subjected to fragmentation processing, the storage requirement of the virus characteristic database is reduced; the sliding window scanning can ensure that any characteristic combination is covered, and a matching event FP i is recorded instead of full data, so that the memory occupation is reduced; through comparison of the absolute offset SB i with an expected position, the correct sequence of the segment in the virus is ensured, a state machine can track the matching progress in real time, and the weight of only the segment with correct sequence is accumulated, so that the detection reliability is improved.

The invention discloses a virus processing method, device and system and a storage medium, and the method comprises the steps: comparing vehicle software mirror image data with a virus template library when the vehicle software mirror image data is received; when the comparison result is inconsistent, judging whether viruses exist in the vehicle software mirror image data or not; when the virus exists, an active confrontation mode is adopted to attack a source server of the virus so as to block a virus transmission source; when the virus is an unknown virus, acquiring feature information of the unknown virus; and updating a virus template library according to the feature information of the unknown virus. According to the scheme provided by the invention, when the virus is found, an active confrontation mode is adopted to attack the virus source server, so that the propagation path of the virus is effectively blocked, and the large-scale diffusion of the virus is prevented, thereby reducing the harm range of the virus and improving the network security.

The embodiment of the invention discloses a method and device for blocking an encryption behavior, a storage medium and electronic equipment. Inserting virtual access information corresponding to a bait file at a starting position of a file list of each directory of directory data information returned by the system aiming at the file traversal behavior; and if a first encryption behavior executed by the target process for the bait file based on the virtual access information is monitored, blocking the first encryption behavior, determining that the target process is a target virus process, and terminating the target process.

The invention provides a terminal virus processing method and system, a medium, equipment and a program product, and relates to the field of network security, and the method comprises the steps: obtaining a network connection behavior of a terminal; matching the network connection behavior of the terminal by using an intrusion index rule, and if a target network connection behavior hitting the intrusion index rule exists, refusing all access requests of the target network connection behavior; and starting a virus clearing strategy and a virus blocking strategy aiming at the target network connection behavior. According to the method and the device, repeated attack and residual of viruses can be effectively prevented, serious problems of system vulnerability, data leakage, system crash and the like possibly caused by the residual viruses are avoided, the resistance of the terminal to the viruses is enhanced, a safer, more reliable and more stable use environment is provided for a terminal user, and the user experience is improved. And the safety protection level of the terminal is obviously improved.
