You may wonder why you need to know how to turn off Windows Defender. Now officially called Microsoft Defender Antivirus, though still better known by its former name, it’s one of the best antivirus programs available and comes completely free with Windows 10. It’s a huge help to anyone who wants reliable protection against malware without the hassle of downloading additional software.
Defender is part of the Windows Security settings interface, which in addition to offering all the usual antivirus protection you’d expect, also lets you activate parental controls, manage the Windows firewall and even set up facial recognition and other biometric authentication to make logging into your PC as easy and secure as possible.
However, while there’s no doubt that Windows/Microsoft Defender is an excellent antivirus tool, there are several situations that might call for you to disable it.
The most notable reason for doing so is that you’re planning to install a different antivirus program on your PC – be it for more features, more in-depth protection options, or simply brand preference. In that case, you only need to install the other antivirus program and Defender will switch itself off.
Another reason might be to install a piece of software that clashes with antivirus protection during installation. This can happen from time to time, but make sure the program you’re installing is legitimate and not just something trying to trick you into installing malware.
Luckily, disabling Defender isn’t a particularly complicated endeavor, but if you need a little assistance, read on for our step-by-step explanation of how to turn it off.
Keep in mind, though, that you should avoid doing any web browsing without some type of antivirus protection turned on. Also know that disabling Windows Defender in this manner is only temporary: when you reboot your PC, Defender will turn itself back on.
