What is a network worm

Network worms generally refer to a type of virus program that exploits computer system vulnerabilities and spreads through the Internet. In order to prevent being harmed by network worms, attention should be paid to upgrading and updating the computer operating system.

Network worm is an intelligent, automated, integrated network attack, cryptography and computer virus technology that does not require a computer An attack program or code that can be run through user intervention. It will scan and attack node hosts with system vulnerabilities on the network, and spread from one node to another node through the local area network or the Internet."

This definition reflects the intelligent, automated and high-tech characteristics of the new generation of network worms.

Preventive measures for individual users against worm viruses

Through the above analysis and introduction, we can know that viruses are not very scary. Network worms mainly attack individual users through social engineering rather than exploiting system vulnerabilities! So beware of such Viruses need to pay attention to the following points:

Purchase appropriate anti-virus software

The development of network worm viruses has made the traditional anti-virus software "file-level real-time monitoring system" Outdated, anti-virus software must develop towards real-time memory monitoring and real-time email monitoring! In addition, in the face of hard-to-prevent web viruses, users have higher and higher requirements for anti-virus software!

Update the virus database frequently

Anti-virus software detects and kills viruses based on virus signatures, and viruses emerge in endlessly every day, especially in the Internet age, where worms spread quickly and have many variants, so it is necessary to Update the virus database at any time so that you can detect and kill the latest viruses.

Improve anti-virus awareness

Don’t click on unfamiliar sites easily, as they may contain malicious code !

When running IE, click "Tools→Internet Options→Security→Internet Zone Security Level" and change the security level from "Medium" to "High".

Because of this Web pages are mainly ActiveX or Applet and JavaScript web files that contain malicious code. Therefore, disabling all ActiveX plug-ins and controls, Java scripts, etc. in IE settings can greatly reduce the chance of being infected by malicious web code.

The specific solution is: click "Tools" → "Internet Options" in the IE window, select the "Security" tab in the pop-up dialog box, and then click the "Custom Level" button, the "Security Settings" dialog box will pop up. , select "Disable" for all ActiveX plug-ins and controls and all options related to Java. However, doing so may make it impossible to browse some websites that normally use ActiveX during future web browsing.
