What should I do if the running software cannot be deleted?

1. Scan and kill the EXE virus that starts the process

1. Single-process EXE virus or trojan programs that can be found in the process, such as svch0st.exe. Some anti-virus software can discover and stop the process and kill the virus; some anti-virus software will trigger an alert to the user or form a log. After further judgment, the user must manually stop the corresponding process and kill the virus.

2. The dual-process EXE virus or Trojan program that can be found in the process cannot be stopped at the same time because of the manual method. After we manually drop one of the processes, another process restarts the process. Anti-virus software is powerless in this case. If both of them are non-system processes, we can stop the process by using the "Task Manager/process/End Process Tree" to kill the virus; you can also use "file/set/prohibit thread creation" in the IceSword tool to stop one process, stop another process, and kill the virus.

If the preceding two methods cannot be "Detachable", you must manually delete the DLL Virus File in safe mode.
