What is ransomware and how to deal with it?

Network security experts advise users to disconnect the network before turning it on, that is, unplug the network cable before turning it on, so as to basically avoid being infected by ransomware. Try to put on a security patch as soon as possible after booting, or install the defense tools launched by various network security companies for this matter before connecting to the Internet. It is suggested that the important files in the computer should be backed up to the mobile hard disk and USB flash drive as soon as possible, and the disk should be saved offline after the backup. At the same time, we should be vigilant against unknown links, files and emails and strengthen prevention.
