Network security defense method and device

Abstract

The invention discloses a network security defense method and device. The method comprises the following steps: network defense system software is installed on a computer; the computer is used to send a networking request to optical modem dial-up networking equipment, and the optical modem dial-up networking equipment activates a dial-up networking function; a browser accesses networking request data and returns a website request carrying a bullet screen and / or a Trojan virus; the network defense system software is started and automatically detects that CPU and memory occupation rates of the computer constantly increase; the network defense system software disables a network, calls a task manager to examine memory abnormality processes and close all process of the browser, and calls antivirus software for searching and killing; and the network is automatically restored after the antivirus software completes the searching and killing. The network security defense method and device provided by the invention has the following beneficial effects: a computer memory can be actively restored, computer performances cannot be affected, and the computer security is ensured.

Description

technical field [0001] The invention relates to the field of network security defense, in particular to a method and device for network security defense. Background technique [0002] In the 21st century, with the advent of the Internet information age, the price of personal computers in China is getting lower and lower, and the cost of accessing the Internet is also getting lower and lower. When computer users visit websites through browsing, they often have network problems. Chinese computer users generally have low computer skills, especially when opening a webpage and clicking on some online reading websites or video websites, the repeated advertisement pop-up windows and newly opened browser pop-up windows make computer users miserable . Pop-up windows and some virus and Trojan horses will be downloaded secretly and will continue to cause system memory loss, and eventually the system will crash and freeze.

Problems solved by technology

Pop-up windows and some viruses and Trojan horses will be downloaded secretly and will continue to cause system memory loss, and eventually the system will crash and freeze

[0003] The most common network security defense scheme in the existing technology can only passively defend and will not actively restore the computer's memory to make the system smooth. On the contrary, the common network security defense system still keeps occupying the system's memory, making the system It becomes very stuck, which affects the performance of the computer, causing many new personal computers to be unwilling to install a network defense system
