    Antimalware Service Executable uses 100% Drive Access


    Version 2004 (OS build 19041.804) For long periods of time this function of Windows 10 (a part of Microsoft Defender) takes up the whole of the spare traffic to and from the hard drive(s). To make that plain, in Task Manager/processes I see 100% at the top of the column and the % for ASE goes up and down to allow other processes to run but takes up all the spare - if others use only 0.8%, then ASE shows 99.2%.
    It also uses up a lot of CPU, but not a lot of memory.
    Obviously this makes the whole PC run extremely slowly, even stationary at times. It particularly affects Chrome but I don't follow why.
    I have a single hard drive but it is partitioned to a C: and G:. Memory is 12GB;
    Can anyone tell me how to prevent this happening? The process cannot be turned off, of course.
    There don't appear to be any background scans running.

    :)
