Problems solved by technology

However, the virus database associated with the antivirus system is generally set to be updated after a certain period of time (such as: 1 day). Therefore, because the virus database cannot be updated at any time, the antivirus system cannot scan in time for the virus being installed. Execution files or virus files in execution files that have been installed and running, thus making the electronic device vulnerable to network virus attacks and causing inconvenience to users

Embodiment Construction

[0016] like figure 1 Shown is a schematic diagram of the hardware architecture of the antivirus system operating environment of the electronic device of the present invention. The antivirus system 10 is installed in the electronic device 1 . The electronic device 1 includes the antivirus system 10 , a memory 11 , a processor 12 , a register 13 , a virus database 14 and a suspected virus database 15 . The virus database 14 includes virus signatures of multiple virus samples, preferably, the virus signatures are signature codes of virus samples, wherein each virus sample has multiple signature codes. The suspected virus database 15 includes a plurality of non-virus characteristics that are easily mistaken for viruses but are essentially safe non-virus samples. Preferably, the non-virus characteristics are the type and name of the non-virus samples, wherein each non-virus characteristic Corresponds to a type and a name. The virus database 14 and the suspected virus database 15...

Abstract

In a virus prevention method of an electronic device, executable files that are being installed in the electronic device are compared with the virus characteristics in virus database of the electronic device. The electronic device communicates with a server through a network, and a virus database and a suspected virus database of the server are accessed when one or more suspected files are determined. The one or more suspected files are compared with virus characteristics of virus samples in the virus database and non-viral characteristic of non-virus samples in the suspected virus database of the server, so as to determine whether the one or more suspected files are virus files. The determined one or more virus files intruded in the executed files are deleted.

Description

technical field [0001] The invention relates to an antivirus system and method for an electronic device. Background technique [0002] At present, the network has become an indispensable tool in people's life. However, when a user uses an electronic device such as a computer or a mobile phone to surf the Internet, or downloads and installs software, he is often attacked by a virus, causing the electronic device to run abnormally and the software to fail to execute. Therefore, users usually install antivirus systems in electronic devices to prevent viruses from invading the electronic devices. However, the virus database associated with the antivirus system is generally set to be updated after a certain period of time (such as: 1 day). Therefore, because the virus database cannot be updated at any time, the antivirus system cannot scan the virus being installed in time. The execution file or the virus file in the running execution file has been installed, so that the electr...
