Windows 10: Windows Defender blocked by a virus

Hi! The past few days I just got a virus really don't know how it was a Trojan and it totally disabled my defender. Also sometimes my windows defender works sometimes not I just restarted my windows and it worked but 3 or 4 hours later it again disables itself. When it worked I removed the virus but still kinda worried that it will show up again. So my main question would be how can i re-enable it back? Really worried and would really really appreciate a help!

Windows Defender is blocking too much saying it viruses

Hi Sam,

Based on the screenshot that you've provided, Controlled Folder Access is turned on, blocking most apps that you're using. We suggest that you turn it off to allow blocked apps in Windows Defender. Follow the steps below:

• Select Start > Settings.
• Choose Update & security > Windows Defender.
• Select Open Windows Defender Security Center.
• Select Virus & threat protection, and then choose Virus & threat protection settings.
• Under Controlled folder access, turn it on or off.
• Once done, try accessing the apps and see if you can now access them.

Should you need further assistance, feel free to post back.
