How to disable Windows antivirus

Do you need to disable Windows Defender to install a program? Here’s how to do it on Microsoft’s operating systems

If you want to keep the security of your notebook or desktop PC high it is essential to use an antivirus that works well and keep it constantly updated. The Microsoft Windows 10 operating system, like its predecessors, integrates its own antivirus software called Windows Defender. It does its job reasonably well, although there are many better free antivirus programs that you can download.

When you install a third-party one, Windows Defender automatically disables it. However, if you need to disable it without having another security software installed, perhaps to test an application that doesn’t work if Defender is enabled, things get complicated. To manually disable Windows Defender antivirus the procedure is different, depending on the version of Windows installed: on Win XP, Win 7 and Win 8.1 Defender is almost a normal application, while on Windows 10 it is tightly integrated with the operating system and Microsoft, normally, does not allow you to disable it. So here’s how to disable antivirus on every version of Windows.

But first a premise: viruses, malware, malicious and fraudulent codes that try to make you fall for scams and phishing of all kinds are now something you might have to deal with every day, especially if you surf online a lot. So if you need to disable Windows Defender, always remember that if you don’t install another antivirus afterwards, you are at a high risk of infection.
