I recently uninstalled Norton and am now unable to reactivate Windows Defender.

In admin command prompt I tried using "sc start WinDefend Enable" but it told me it could not verify the digital signature.

I tried changing the Windows Defender Service startup type to automatic.

I also tried a system file check and it said that there were corrupt files it cannot fix, the log from this is attached below.

I would like to resolve this issue without having to refresh or reset windows any and all help will be appreciated.

If a third-party trial anti-virus came preinstalled on your computer or you installed one yourself, it most likely turned Windows 8 Defender off (disabled) to avoid conflicts since it includes anti-virus protection. Windows 8 Defender will remain disabled until that anti-virus software has been completely uninstalled and then Windows 8 Defender needs to be activated if you choose to use it.

Did you follow these instructions?...Norton Removal Tool to uninstall your Norton product (Windows all versions)
Did you run the Norton Removal Tool?

If not, please do so, reboot, then refer to these instructions.

Okay so I'm a bit confused; the screen in the action center that your links show was not the one that I had, mine only said stuff about turning on Windows Security Center. I looked it up on google and did that and now I'm at the screen that they show in your links for the action center however mine also has one that says my Network Firewall is off or set up incorrectly. When I click to turn on the spyware or virus protection it just opens the system32 folder and when I click to turn on the firewall it says it can't do it automatically and that I have to do it manually but when I open that thing all that shows up is the button to use recommended settings and that button just pulls up the exact same recommended settings button again when clicked.

I'm pretty sure somewhere along the way I bleeped up my system real bad and I have no idea how to fix it. I seem to have made some progress but I still need a ton of help.

Thats what mine looks like but whenever I click to turn the virus protection or the spyware one it just changes the window into the system32 folder, when I click the firewall one it opens the thing below.Screenshot_67.png

And when I click to do it manually it opens this.Screenshot_68.png

And when I click pretty much anything on that screen it just opens the same screen again.

Did you run the Norton Removal Tool?
If not, please do so and restart the computer.


Press the WINKEY + R keys on the keyboard or click the Start Orb > Run... , and in the Open dialog box, type: services.msc
Click OK or press Enter.
Check if Windows Firewall service is running and set to Automatic.

If it is....Stop and then Re-enable.
If, not...then just click Start.

Repeat the above and check if the Security Center Service is running and set to Automatic...How to Start/Stop Security Center service

I did run the norton removal tool. What you said to do seems to have fixed the firewall bit. I actually already had to fix the security center service just to get it to tell me the firewall was down.

Did you check in services to make sure the Windows Defender 8 service was running (enabled)?

Press the WINKEY + R keys on the keyboard or click the Start Orb > Run... , and in the Open dialog box, type: sc start WinDefend Enable
Click OK or press Enter.
Restart your computer.
Then try opening Windows Defender again.

"This app has been turned off and isn't monitoring your computer...use Action Center to check that app's status" is typically the message provided when attempting to run Windows Defender on a system where a third party anti-virus is installed.

windows-defender-turned-off.png

Go to Control Panel > System and Security > Action Center and you should see a red alert indicating "Spyware and unwanted software protection (Important) Windows Defender is turned off [Turn on now]."

Click the "Turn on now" button and the Windows Defender screen should turn green and say "Your PC is being monitored and protected...Real-time protection: on." Please be patient as sometimes it may take a while for Windows Defener to turn itself on.

action_center10.png

Click the "Update" tab to view the virus and spyware definition update status indicating when virus and spyware definitions was last created. If it has been a while you should see a message indicating "Your virus and spyware definition haven't been updated lately...You should update them now to help protect your PC."

Click the "Update" button so Windows Defender can download the latest definitions. After completing the update, the status will change to "up to date"" and allow you to perform a scan.

If that does not work, see these suggestions...The last two users in this topic posted alternative solutions for taking Full Permissions Control To Edit Protected Registry Keys which worked for them. Always Create a New Restore Point and back up the registry before making any changes.

If this still does not work, you may have to switch to another anti-virus solution or:
Repair Install Windows 8 (refresh and reset)
How to refresh, reset, or restore your PC
