Hi krausetl44
 
Welcome to the Community Forums.
 
If I may just add for clarification...in the past the installation fo a 3rd party AV or AM app would have automatically disabled/switched off Windows Defneder, but as of a recent WIindows Update this policy has now been revoked by Microsoft and it now remains active.
 
Whether to leave it enable or disabled is a personal decision and indeed some would say that its detection rates and the protection that it offers these days makes it an excellent additional layer of security and/or a good 2nd opinion scanner.
 
Indeed even when turned off you can configure it to peridically carry out a scan of your system and then switch itself off a again...whichihs a nice & automatic double check if one wants it.
 
Hope that assists further?
