Strengthening self-prevention awareness is the first step in our defense against cyber threats. In this article, we will introduce the prevention awareness that needs to be strengthened during the normal use of the network in 11 aspects.

1. Prevention first

2. Get protected

If virus protection software is not installed on your machine, you'd better install one. If you are a family or individual user, downloading any of the best-ranked programs is fairly easy, and you can follow the installation wizard. If you are on a network, first consult your network administrator.

3. Scan your system regularly

If you happen to start antivirus software for the first time, it is best to let it scan your entire system. It is a good thing to start your computer cleanly and without virus problems. Usually, the antivirus program can be set to scan the system every time the computer is started or run on a regular schedule. Some programs can also scan the system in the background when you are connected to the Internet. Scanning the system regularly for viruses, it is best to become your habit.

4. Update your antivirus software

Now that you have virus protection software installed, you should make sure it is up to date. Some anti-virus programs have a function to automatically connect to the Internet and add new virus detection codes whenever a software manufacturer finds a new threat. You can also scan the system here for the latest security update files.

5. Do not easily execute executable programs such as EXE and COM in the attachment

These attachments are most likely to carry computer viruses or hacking programs, and run easily, which may bring unpredictable results. Executable program attachments in e-mails sent by friends and strangers you know must be checked, and they can be used only when they are the same.

6. Do not easily open the document file in the attachment

The e-mail and related attachment documents sent by the other party must first be saved to the local hard disk using the "Save As ..." command ("Save As ..."), and can be opened for use only after the anti-virus software checks the virus-free. If you directly click on the DOC, XLS and other attachment documents with the mouse, Word or Excel will be automatically enabled. If there is a computer virus in the attachment, it will be transmitted immediately; if there is a "Whether to enable macro" prompt, it should never be opened easily, otherwise It is very likely to be infected with e-mail computer viruses.


7. Do not run accessories directly

For attachments with strange file extensions, or attachments with script files such as * .VBS, * .SHS, etc., do not open them directly. Generally, you can delete e-mails containing these attachments to ensure that the computer system is not affected by the computer Virus infringement.

8. Mail settings

If you are using Outlook as your email sending and receiving software, you should make some necessary settings. Select the "Options" command in the "Tools" menu, set "Security" of the "Accessories" to "High" in "Security"; press the "Advanced Options" button in "Others", and press the "Add-on Manager" button, Uncheck "Run Server Script". Finally press the "OK" button to save the settings.

9. Use the preview function with caution

If Outlook Express is used as the e-mail sending and receiving software, some necessary settings should also be made. Select the "Options" command in the "Tools" menu, and uncheck "Automatically display news messages in the preview pane" and "Automatically display picture attachments in news messages" in "Reading". This prevents some e-mail computer viruses from running automatically using Outlook Express's default settings and destroying the system.

10. Uninstall Scripting Host

For computers using the Windows 98 operating system, select "Add / Remove Programs" in the "Control Panel" to check whether Windows Scripting Host is installed. If it is installed, please uninstall it, and check whether the Wscript.exe file exists in the Windows installation directory, and delete it if it exists. Because some e-mail computer viruses are destroyed using Windows Scripting Host.

11. Be wary of outgoing emails

Attachments that you send out must be carefully checked to ensure that they are non-toxic before they can be sent. Although e-mail computer viruses are quite terrible, as long as they are properly protected, computer viruses can still be avoided, and they can still be used with confidence.

Through the above descriptions of worms and the symptoms of their outbreaks, I believe everyone has a deeper understanding of them. Because worms are spread through the Internet, in today's highly developed network, worms are invincible. Only by building a firewall on our computer and developing good Internet habits can we minimize the damage.
