It may have been infected with a virus.
Just manually killed the virus. Let's summarize how to kill the virus.
The fastest and most thorough antivirus:
1. Disconnect from the network.
2. Open the "Task Manager", there should be a process, end it. Go to C: Windows System32 and find it to delete it.
3. Run "Start" "Run" and enter "regedit" to open the registry.
4. Find the checkedvalue in the hkey local machine software microsoft windows currentversion explorer advanced folder hidden showall, check whether its type is reg dword, if not, delete the checkedvalue, and then right-click "New"-- dword value" and name it checkedvalue, then modify it to a key value of 1. (If you don't do this, you won't be able to view the hidden system files in the first step.)
5. Open each hard disk (right-click "Open" or "Explorer" in "My Computer" and select it), 6. "Folder Options" "View" select "Show all files and folders", and remove the "Hide Protected System Files" checkbox.
7. You can see that there are files in the root directory of each hard disk, and delete them. If you also have it on the USB flash drive, delete it as well. The USB flash drive may be deleted and will appear again, then check whether there is a process in the "Task Manager" and end it (see 2).
8. That's pretty much it.
9. If you install Rising Rising, the firewall and anti-virus software should be able to be opened, and other anti-virus software should also be opened.
10. If the Rising computer monitoring cannot be opened, or the little red umbrella is closed after opening, and all the monitoring has failed, then go to the "Control Panel" "Management Tools" "Service", find "Rising Process Communication Center", it should be disabled, right-click "Properties", change the startup type to "Automatic", and then enable the service.
11. At this point, the computer is back to normal.
