How to uninstall Windows Defender?

If you no longer want to use Windows Defender, it is recommended to just disable it, and do not uninstall the program. Action is possible, but you risk deleting folders or drivers that are part of the operating system. In addition, a Windows Update update in the future is very likely to restore Windows Defender and undo the action.

In addition, both disabling and uninstalling are indicated only if you install another type of antivirus on your computer immediately. Leaving the machine unprotected facilitates cyber attacks that can steal important personal data, such as passwords and credit card numbers.

Action occurs precisely to avoid conflicts between the software, as an antivirus can detect the other antvirus as a threat, causing the computer to slow down or even crash. If you want to activate Windows Defender again, simply uninstall any other antivirus programs that are installed on your computer.

Incidentally, even if you choose to use another antivirus other than Windows Defender, you can still manually use the Microsoft program to scan your computer for suspicious files.
