Defender for Endpoint (mssense.exe) locking files and causing issues
Hi, We have encountered an issue with one of our applications whereby every time the application downloads a file from the application server, mssense.exe creates a RWD lock on the file very briefly...
The issue has been resolved, in the end it wasn't the file locks or anything to do with Defender. It was an issue with the application. Got it working without needing to change anything in Defender.
Thanks for all the help regardless.
MSSense is the primary process for the functions of MDE outside of antimalware scanning. It isn't surprising that it might look at new files on the system, it is gathering information on the files like hash, digital signatures, etc. As far as I know, there is no exclusion that applies to this functionality, though I did see in a posting about this issue from a few years ago that Microsoft support has the ability to create exclusions for this. I say try opening a case.
