Stay alert! How to prevent new Network Viruses

More and more viruses are spreading through various channels of the internet, and new malignant viruses are no longer designed to reserve a period of time for enhanced transmission. They will attack immediately after recruitment. A new virus can be found around the world in hours to days.

ActiveX Control and Java code

Adding ActiveX controls and javascripts code on the webpage can enhance the attractiveness of the webpage, And the browser can download or run corresponding programs from the browsed webpage. In general, these programs can run securely. However, when your browser vulnerabilities are not fixed, you are vulnerable to malicious code damages. The reason may be that you click a message sent by a netizen on QQ.

The method to prevent attacks is simple, as long as you fix the vulnerability in time. Windows Update is generally used, and some anti-virus software also provides patches. It is also important to correctly configure the security options of the browser. When the ActiveX control appears, a message box is displayed in the browser asking if you want to accept the control.

We recommend that you disable Java programs. For IE, You need to select [tools] → [Internet Options] → [security], press the [Custom Level] button, and drag the scroll bar until you see the Java Settings section, click [disable. From experience, intermediate settings are the best security settings for surfing the Internet.

If you have fixed ie correctly, a warning window will pop up asking you if you want to download the program embedded in the web page. If you are not sure about its purpose, it is recommended that you do not download it.

E-mail Virus

E-mail is still the main channel for new virus intrusion, because E-mail has almost no security control mechanism, and many people have been very hasty to open attachments in E-mail. Some viruses (such as the cover letter virus) can automatically open attachments using the Outlook vulnerability, which is more dangerous. We recommend that you do not open the email client if you are not sure about the purpose of the attachment when using E-mail, and pay attention to the frequent patching of the mail client program to avoid automatic opening of the virus by exploiting the vulnerability. Using the mail firewall to filter emails is also a good choice.

Instant chat and point-to-point tools

Chat tools QQ, ICQ, and MSN are the favorites for instant communication among netizens. The "Hunters" trojan uses QQ to publish messages so that your chatbots can become popular. The Application of P2P transmission tools makes it very easy for users to communicate with document software, but it hides a large number of security risks. The latest Worm. Fizzer Worm uses the KaZaa tool to spread a large number of files in shared files. It also integrates hacking methods. I believe there will be more viruses that will continue to use software like P2P. The same applies to shared resources in the LAN. You should set permissions for all shared resources to minimize write sharing.

When using network resources, be alert. Do not trust the Internet users. Click the relevant link. We recommend that you set the folder in the resource manager to view all files and display the file extension, do not take executable files lightly. No one can predict the consequences of an unknown program running. That is, the antivirus software has been used for inspection and should not be executed easily. I believe that the number of times viruses harass you will be greatly reduced.
