Strengthening the awareness of self-defense is the first step for us to defend against cyber threats. In this article, we will introduce 11 aspects that need to be strengthened in the process of using the network.

If you are a home or individual user, it is quite easy to download any program with the best ranking, and you can follow the installation wizard. If you are in a network, first consult your network administrator.
3. scan your system regularly. If it is the first time you have started anti-virus software, you 'd better ask it to scan your entire system. It is good to start your computer clean and virus-free.

Some programs can also scan the system in the background when you connect to the Internet. It is best to regularly scan the system for viruses.
4. Update your anti-virus software. Since you have installed the virus protection software, make sure it is up to date. Some anti-virus programs are automatically connected to the Internet, and new virus detection code is added as long as the software vendor discovers a new threat. You can also scan the system to find the latest security update files.
5. Do not easily execute executable programs such as EXE and COM in the attachment. These attachments are very likely to carry computer viruses or hacker programs and run easily, which may bring unpredictable results. Execute Program attachments in e-mails sent from friends and strangers must be checked and confirmed to be usable.
6. Do not open the electronic mails sent by the recipient and the documents of the relevant attachments. First, use "Save ..." Command ("Save ...") Save it to the local hard disk.

Select the "options" command in the "Tools" menu, and do not select "automatically display news mails" and "automatically display picture attachments in news mails" in "read ". This prevents computer viruses from running automatically using the default settings of Outlook Express to damage the system.
10. Uninstall Scripting Host. For computers that use Windows 98 operating system, choose "Add/delete programs" in "Control Panel" to check whether Windows Scripting Host is installed. If the installation is completed, uninstall it and check that the wscript.exe file exists in the Windows installation directory. If yes, delete it. Some email computer viruses are damaged by using Windows Scripting Host.
