Starting with the following points, computers are not prone to poisoning:

1. Use the new version of the operating system (PC install win10,Server install Win2019)

two。 Apply all patches (with 360 patch tool)

3. Set the computer as a strong password

4. Turn off all unused ports

5. The safest way to deal with it: [back up important data once a day. ]

6. At present, all blackmail viruses target the Windows operating system.

It is recommended to back up important data to the Linux host (linux enables ftp service, and regularly backs up important data to linux's ftp) to ensure data security.
