Because the running program is protected by Windows, viruses are often killed and cannot be deleted even if they are found. Antivirus software kills the virus how to do? It used to be recommended to kill in Safe mode or DOS mode. Now there is a new method called "Specify the debugger in the image File Execution option", and it should be possible to disinfect it in this way. The principle is to modify the re
