Anyone have any idea on how to fix this? I can’t disable Windows defender through the program and so far haven’t found anyway to fix this problem 
Any support would be very much appreciated 
Specs: Windows 7 Home
Avast Free Antivirus
Open your start menu and type/copy-paste services.msc into the run menu, scoll down to Windows Defender and double click to open then set the startup type to Disabled and click Apply to finish.
Yea that’s what I normally do, I just thought there was a way to fix the error, thanks anyways…
Do you have any other security installed on the system or old security software that hasn’t been completely uninstalled http://answers.microsoft.com/en-us/protect/forum/mse-protect_scanning/error-code-0x8002801d-library-not-registered/4a02f8e1-baf7-4469-97ad-3526573e146c
