    Windows Explorer slow in opening files and folders

    Since a couple of weeks when I open a file or folder in my Windows Explorer i see for maybe a couple of seconds a wristwatch pointer appearing and disappearing before opening that file or folder.
    Not a big deal but annoying.
    Can anyone help me please?

    So many questions. Is this an internal t external drive. Have you started sharing the folders? Did you turn on the option to show folder sized in tooltips?

    Thank you for your answer.
    1. it happens with internal drives (no USB or NAS drives)
    2. I do share a folder but I always did even before the problem occurred
    3. I didn't turn on the option to show folder size

    When did this start happening? Did you install any 3rd party software since then? Have you tried a System Restore to a time before this started happening?
    Try doing a Clean Boot. If that works, add one startup item or service and reboot until the behavior returns, then you will know with the problematic program is.

    Thank you.
    I am certain I installed 3rd party software but I can't remember when the problem started so a System Restore may be difficult.
    But a Clean Boot is certainly an option.
    Thank you very much: I'll give it a try and post the result (not today but probable next week)

    As it happend it was my anti-virus program Malwarebyte that proved the culprit.
    Now I am running only Windows Defender.
    My PC is faster than ever.
    Has anyone else know of this behaviour?

    @aliskander. Hi, some time ago, I noticed that my laptop became sluggish as I began experiencing the same behavior you mentionned. Mouse pointer truns busy when browsing disks and folders in Windows Explorer, web browsing slow, app lauch slow, etc. I tried everything: registry cleanup, system cleanup, acronis backup restore dating 2 months ago... nothing helped! I couldn't suspect that MBAM 3 could be the problem. I have been using MBAM for 3 years now w/o real issue. I uninstalled it and waou: my laptop is now lightning fast. I went to MBAM forum and found out that this is an issue for others users and that MBAM team is aware of that. I now have to wait for a fix since MBAM seems to be the best securtiy tool IMO.
