    what does MsMpEng.exe actually do???


    All,

    I'm looking at some horrendous performance issues with our Windows 10 environment. Whilst the estate is old and low on resources in a lot of cases I don't think Windows 10 is helping matters. I'm using the usual tools (procmon, perfmon, task manager)to try and get to the root cause but there seems to be a myriad of issues.

    One thing I have noticed is that MsMpEng.exe (part of defender I believe) is continually running against a whole bunch of files and getting fairly long disk response times.

    Question is what is this doing running??

    :)
