Once it is finished we can restart the system and see if Windows Defender now starts correctly. What it does is review possible corrupted files and correct them. This may take more or less depending on our equipment, the number of files, the power, etc. Once we are inside, we have to execute the scf / scannow command. We can go to Start, look for Command Prompt and run it with administrator permissions. To do this you have to enter the Command Prompt or command line. This problem usually has an easy solution, since Windows itself has a command that we can execute.

Sometimes there are corrupted files that prevent applications from starting such as Windows Defender.

This happens when we install a program and it creates a conflict or even a virus that may affect the registry. It can also happen that there are corrupted files in the system. This will allow us to have the equipment with the latest versions and thus correct possible errors that appear, but also make sure that nothing has been pending and is the cause of these blocks.

They will also show us possible patches that have been left unfinished and that we will have to update manually. What we are going to do is go to Start, we enter Settings, we are going to Update and security and, once inside, it will start looking for new updates. It could have happened after installing an update of the antivirus itself or of the operating system and it has hung. Check that everything is up to date wellД¬ould there have been any error with some update? Undoubtedly this cause could cause Windows Defender to crash. We must verify that everything is in order and that it is not causing problems of any kind. Sometimes it interferes with other security programs or whatever applications you have installed. Something similar could happen if we have a firewall installed. This way you will be able to check if the Microsoft antivirus starts correctly, since it could be being blocked by the other program. If for example you have Avast, Bitdefender, Kaspersky or any another antivirus installed next to Windows Defender, it is best to disable it. In reality, what can happen is that a conflict is created and neither of them works correctly. This is not a good idea, although some users may think that if they have two antivirus they will be more protected than having only one. One of the main causes of problems of this type is having more than one antivirus installed.
