Technically you shouldn't worry, as the update should install automatically, but Microsoft still recommends that you manually check for available updates on a regular basis to make sure you don't run into such problems. In any case, below we list the steps to check the version of Microsoft Malware Protection Engine currently installed on your system, taking as a reference the fact that the latest version to be affected by the bug in question is the 1.1.17700.4.



  1. In the search bar, type "Windows Security" and click on the first result.
  2. Once Windows Defender is open, click on the settings icon highlighted in the picture.
  3. Select the item “About”.
  4. Check the entry "Engine version", which is what interests us in this case.

It hasn't been too long since Microsoft had to fix another bug related to the security of its systems, which allowed anyone who could connect remotely to start any program they wanted to. Could it be worth checking out Windows Defender, rather than going ahead and patching it up every time a minor problem arises?


If you want to ensure greater security for your system, we recommend the Norton 15 360 2021-month license currently discounted by 68% on Amazon!
