Windows 10: Windows Security not opening neither antivirus system turning on microsoft defender app...

Windows Security not opening neither antivirus system turning on microsoft defender app also not opening help me to protect my laptopi had tried so many times windows security not working at all no antivrus turning on no microsoft defender working . plz provide me help

Microsoft Defender VS Microsoft Defender Antivirus?

Today, I uninstalled the Microsoft Defender app on my device.

However, in Windows Security > Virus & threat protection > Security providers, Microsoft Defender Antivirus is listed as my Antivirus.

When I click on "Open app" for Microsoft Defender Antivirus, it just redirects me to Windows Security > Virus & threat protection.

1. Is Microsoft Defender Antivirus different from the Microsoft Defender app?

2. Is my device still being protected?

For context, I do not have any third party antivirus programs installed on my device right now,

and I never signed into the Microsoft Defender app with my Microsoft account,

nor do I have a Microsoft 365 subscription.

 

"Attestation" A new feature coming to Windows Defender in Windows 10

Tech Republic - Upcoming Windows Defender feature will tell you when security fails

This seems very promising. Microsoft is in the unique position to know what Windows should look like, even before Windows Update pushes out new changes. As long as MS can properly sync WD with WU changes AND this new features does not make any "noticeable" hit on system performance/resources, all without any false positives, this should be a big step forward for consumer security, and a blow to the bad guys - always a good thing.

Of course, there will likely be some hiccups the Windows/Microsoft/Windows Defender bashers will surely pounce on - regardless how extensive the Beta process is. But hopefully open and unbiased minds will prevail. After all, the goal is to stop the bad guys and if this gets us closer to that, that's a very good thing.

Will Windows Defender turn itself on

After Norton expires, restart (reboot) the system. Defender should automatically turn on. Opening Defender (in search, type DEFENDER. App will be at top) should look like this.





If Defender is off, it will look like this. Click Turn On. You may also receive a notification banner in lower right of desktop.

As a side note, if Norton is set to expire in a couple of weeks (around month end), you may want to consider just disabling it now and uninstalling and setting up Defender. On 8/02/16, there is a major Windows 10 update scheduled. Just a suggestion to avoid having to deal with both at the same time. TC
