Windows 10: My computer is blocked. windows defender security center pop up how do i fix this

Access to my computer has been blocked by a Trojan Spyware pop up that says Windows Defender Security Center, access to this computer has been blocked for security reasons. It will not allow me to operate my computer at all, so all of the remedies I have been finding are of no use. I am not a computer wizard, so any explanation would have to be rather in its simplest form. I am writing this from a different computer. Thank you, Phil

windows defender & security center services keep turning off


Are you running any other AV or did you have one running in the past? If you didn't use an uninstaller for the AV, then the remnants of it could be causing the problem. Normally any time you install an AV it disables Defender by default.

If you are getting any error codes please list those, that will be helpful in helping you.

As torre suggested, might be a good idea to do a reset or even a reinstall.

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.
