Linus system blackmailed by bitcoin

In my opinion, I don't know if it's right. We still need criticism and correction. I don't think this virus has anything to do with which way you use to access the Internet, and it also has nothing to do with which kind of computer (PC or laptop) you use. He mainly aims at some loopholes in the Current Windows operating system. We all know that when a software is downloaded, it must have the highest administrator authority to install the software on this computer. This should be a security policy of the computer operating system. However, there are loopholes in everything, and the operating system is no exception. For example, this virus outbreak, in fact, the patch was released as early as March, but many users didn't pay attention to it and didn't fix it. So, now as long as you are connected to the network, and the system vulnerability is not repaired in time, you can scan the port, use the vulnerability of a port, directly install the encryption software (virus) to your computer in the background, and encrypt your important files, so as to achieve the purpose of blackmail. So it's better not to turn off the self-renewal function of windows for convenience. At the same time, it's also recommended to turn off some ports that are not often used but are very dangerous, such as 445, 135, 137, 138 and 139—— Finally, WiFi is just a way to access the Internet. It can also spread viruses. So, quickly update and patch it .... There is also a video here. I think it's very good, but I don't know if I can watch it http://weibo.com/tv/v/?fid=1034 :
