Windows 10: A Virus Disabled Windows Defender Security Center and I Can't Re-Enable it

I downloaded a file from YouTube and opened it... it asks for administrative privileges, which is normal. I gave it admin privileges and it immediately started installing over 20-30 apps, viruses, and changing system settings. I quickly turned Airplane mode on, I opened Task Manager and disabled all startup apps, closed most app installers, and noticed a notification saying "Windows Defender Virus Scanner is not running.", so I restarted my PC hoping it would startup (I didn't disable automatic startup for it) when my PC booted I tried to run Windows Defender Virus Scanner to fix the problems, and it says, "PAGE NOT AVAILABLE: Your IT administrator has limited access to some areas of this app, and the item you tried to access is not available. Contact IT helpdesk for more information." I closed the Pop-up and went to Virus and Threat Protection, and all settings are disabled. What does this mean and how exactly do I fix it, and can I fix without cleaning my Hard Drive? I cleared all the installed apps and most virus files.


If you need the app names which changed settings...

soldier.exe

Intercoastal.exe

They were both opened 7-8 times each, and still has 7-8 Auto-Startup Icons, I deleted each 3-5 times

(Multiple Locations)


App that I think is a Virus...

YzU1YmNlNTNjYWJhY.exe

(Location is in C:\Program Files\ZWY2ODhlMzIwNTM4YjF)


App I'm not sure about...

gdapgutsvc.exe

(Location is in System folder, unsure which one)

windows security center disabled...

windows security center disabled????????

i just installed windows defender on my computer (freshly formated new hard drive about 2 weeks ago) and it would not update because the security center was not running. so i went to msconfig and it was not in the services list so i went to services.msc and it was disabled. so i changed it to automatic and started it. after rebooting it was still running, so i restarted it again and it was disabled again, so i renabled it again. and when i went to the security center in control pannel it looked like this





i had to enable the windows firewall too. but it says that automatic updates are turned off, so i went to change it and it said that it was on...???...???? i did the fast format this time cause i didnt want to wait for 500gb to format *Big Grin and i have noticed a few other quirks mainly my audigy 4 pro software acting funny time to time. do you think that i have a virus or something of that nature? i will put AVG on here tomorrow and maybe adaware. i have never had a virus so i didnt see any need for anti virus and or spyware programs eating up resources. but i am puzzled as to why my services are automatically shutting down...

 

Disable Action Center in Windows 7?

Unfortunately that doesn't disable Action Center, all it does it cause Acution Center to bitch about the Security Center service not running.

Action Center seems to be a different beast from Security Center...

And telling it to not display any messages gets it out of the way, the same way disabling the icon in the suggestions above does, but Action Center is still enabled and running.

 

Windows defender couldnt be enable after being disabled

Hello Imtiaz,

Thank you for posting the query on Microsoft Community.

I appreciate your interest on Windows 10.

Before we proceed I would like you to answer the following questions:

• 
  Have you installed any third-party security software on your computer?
  
• 
  Are you using administrator account?
  
• 
  Is the computer connected to domain?
  
• 
  Did you try restarting the computer and check?
  

I suggest you to follow the methods below:

Method 1

update the group policy and check.

• 
  Press Windows key + R.
  
• 
  Type Gpupdate and press enter.
  
• 
  Then try enabling the Windows defender in group policy and check.
  

This issue usually arises when you have installed a security software on your computer. From Windows 8 onwards, the Windows Defender is equipped with all the functionalities of an anti-virus software including real-time protection which was not
present in Windows Defender in Windows 7.

Method 2

If you have any third-party security software installed, I would suggest you to uninstall thatsoftware and then upgrade to Windows 10. As it is not recommended to keep more than 1 anti-virus software with real-time protection.

Important Note: Antivirus software can help protect your computer against viruses and other security threats. In most cases, you shouldn't disable/uninstall your antivirus software. If you have to temporarily disable/uninstall
it to install other software, you should re-enable it as soon as you're done. If you're connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.

Whenever you install a third-party security software in Windows 8.1 or Windows 10, it automatically disables Windows Defender to avoid conflicts.

Method 3

I suggest you to follow the steps below to turn on the windows defender.

• 
  Type control panel in the search box.
  
• 
  Choose the Action Center under
  System and Security option.
  
• 
  You see the notification that Windows defender is turned off below the
  Security label. Hit the Turn on now tab to active the Windows Defender again.
