Severity Rating: Critical Revision Note: V2.0 (August 8, 2017): To comprehensively address CVE-2017-0071, Microsoft released the July security updates for all versions of Windows 10.
When I browse through forums I often find this question asked many times – I am unable turn on Windows Defender manually in Windows 10, Windows 8 or Windows 7 – or Windows Defender won’t or will not turn on and start.
Scenario 1: On of the most common behavior of Windows Defender is that if it detects a third-party antivirus software, then Windows Defender will shut itself off.
So in case you want Windows Defender to work, then you will have to uninstall your third-party security software and reboot the system.
Often users maybe unaware if a security software is indeed installed or not because when you buy a new laptop, mostly it comes with a trial version of security software like Norton, Mc Afee, etc.

It is assumed that Sophos will continue to run on Windows systems prior to Windows 7 SP1 but this has not been tested.
Contact your network administrator to make sure the proxy server is working.
If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
So to avoid this situation, Windows Defender will turn itself off when it detects another security program.
Likewise, if this security application has a Firewall, then Windows Firewall will also stop working.
