Windows Defender started off as spyware protection in Windows XP. By Windows 8 it had turned into reliable full-fledged antivirus for your computer. In Windows 10 many people regard Windows Defender to be up there with the best protection your Windows operating system can have.
Not long after the release of Windows 10, Windows Defender was renamed as Windows Security. This can be noted by the various places you would expect to find Windows Security links, such as in the Start menu. It still offers all of the same antivirus protection and begins operating automatically so there’s nothing you have to do but sit back and enjoy using your computer. It even runs its scans automatically periodically so you don’t have to worry about that either.
Windows Security works best when you have Windows Update enabled and accepting software updates. This is because the definition files for the antivirus are updated when you get regular software updates from Windows Update. It’s these definitions that allow for Windows Security to always be up to date with detecting the latest potential threats for your computer. If you temporarily turn off Windows Security, it will automatically turn itself back on again so it doesn’t mater if you forget. That way you can continue getting scan and updated definitions.
While not a necessity, some people like to use a combination of Windows Security and another antimalware program such as Malwarebytes. This is because you can only ever have one antivirus program installed at a time, but Windows Security can work alongside another antimalware program.
There’s no need for you to shop for other antivirus protection. However, if you want to swap Windows Security for another third-party program, you shouldn’t turn off Windows Security before installing the new software. Windows will automatically turn off the older antivirus as soon as you install the new one, so that way you’re never browsing the World Wide Web without protection. While using anti-virus protection from a third-party, it’s normal to find Windows Security turned off. If you want it back on again, then uninstall the third-party antivirus, and it will come back on automatically the next time you use the computer.
Windows Security works by offering your computer two kinds of protection: Real time protection and the option to scan the computer at anytime. Real time protection means that you are notified when malware tries to install itself on your computer. It also means that Windows will prevent that from happening. The option to scan anytime means you can choose a scanning schedule or even enter Windows Security and choose to run a scan manually whenever you want.
