Norton vs Win: Defender does not play nice

This is an ongoing struggle. Windows defender turns the simple act of logging in to my computer into an extended experiment in human patience. I Effing hate windows and am feeling myself turn into a Mac user as I type this. I have Norton anti virus and it takes care of my security as I have set it to do so...However, Defender keeps trying to turn on and fight Norton which causes my computer to slow down to 1980's level usage. 

Windows also seems to feel it is their responsibility to prevent you from turning off the service. Every time I log in the service restarts, Since it literally can take me 15 minutes to turn it off and restore my computer to it's previous speed... I find this to be something that is not just obstructive...but also a sound argument to write of MS all together. 

The solution I have found (for anyone that does not have a group policy)... Is to disable it through the regedit.


Before diving into this guide, it's worth noting that editing the registry can be dangerous, and it can cause irreversible damage to your system if you don't do it correctly. It's highly recommended to make a full backup of your system before proceeding. You've been warned!

  • Use the Windows key + R keyboard shortcut to open the Run command
  • Type regedit, 
  • click OK to open the registry.
  • Browse the following path:  HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
  • If you don't see DWORD DisableAntiSpyware, 
  • Right-click on an empty space, 
  • Select New, 
  • Click on DWORD (32-bit) Value.
  • Name the key DisableAntiSpyware.
  • Double-click the newly created key, 
  • Change the value from 0 to 1.

If you want to re-enable the defender...set the value back to 0.

NOTE: You should only do this if you are having conflicts with your EXISTING anti-virus software and windows defender.

This is a process I followed and it worked for me. I am circulating this blog because I think it is important to get the information out for those that are suffering from this issue.
