<p>Some of the reported issues in the previous month include very high memory usage, and black screen issues with two-minute delays after logging in. Word 2016 and newer versions fail to open or it takes a long time to open.</p>
<p>A high memory usage issue is caused by Defender&#8217;s Antimalware Service Executable process (MsMpEng.exe). Luckily this issue can be mitigated by disabling the Real-Time protection, although you won&#8217;t do that if you want to stay protected.</p>
<p>Unfortunately, these issues were not the only problem Microsoft Defender is having recently. In the recent Awards, rating Defender was by a hair&#8217;s breadth managed to secure the Standard rating along with Total Defense AV.</p>
<p>Awards tests included File copying, archiving and unarchiving, installing, uninstalling, and launching applications, downloading files, and browsing websites.</p>
