    Is KB915597 Safe?


    Is KB915597 Safe? It’s labeled as ‘Definition Update for Windows Defender - KB915597 (Definition 1.225.2702.0)’ in the Windows Update window.

    There are several reasons I ask. First, is this is the very first time Windows has notified me that an Update is available since they snuck in the Free Win 10 Update (3035583?); I’ve had to go into the Control Panel ever since to check for updates.

    Second, when I clicked on More Info, I got a browser window talking about Win 10 and not Windows Defender.

    And then I Googled KB915597 and found tons of folks having trouble with it, including not booting after installation. I also found a post calling it a ‘legacy’ update. But then I noticed all those I found were many years old.

    I did find it on Microsoft’s Web site, but it says it hasn’t been updated since 2010!?

    With all the sneaky updates MS has been installing lately, I’m very suspicious about this one.

    Any thoughts on this?

    Hi,
    You use Avast or at least that is what is listed in your system spec's,
    If so windows defender should be disabled and there by these defender updates would not appear as updates.

    Advice: Go straight to Microsoft website to understand the meaning on this KB915597 and not other threads.

    Do note that it is best not to read into other forum &or posts, as each user may differ.
    In the end, you are now confused on this matter, which should not happened, do read below,fyi.


    Go to Control Panel --> System & Security --> Windows Firewall.
    As what #ThrashZone mentioned, that antivirus may conflict with Windows Defender.

    To avoid this, read below fyi.


    -------------------------------------------------------------
    For your info.

    Did you set the option on the Windows updates to "Download updates and let me choose whether to update them"

    Try to use this option, instead "Install updates automatically (Recommended)"
    In this way, Windows will updates important updates when necessary.
    Hence you would not need to consider to update or not.

    The reason is that what would happened that you go ahead and install an updates, which may not be necessary, and hence it may create certain issue.
    I used that option "Download...choose..update", that created more problems as i am not sure it is useful to install the update or not.

    By using the recommended option, i do not have any problem on to install updates or not.
    Hence, the system is very stable than previously.

    Hi ThrashZone. Yes I've been using Avast for many years now, and also Windows Defender. I've never had a problem with them working together.

    Hi Eric. I did find it on Microsoft’s Web site and that was part of my confusion: it says it hasn’t been updated since 2010. I guess they (MS) don't take the time to update the 'last update' info.

    While I was clacking all this out, I opened Windows Defender to see what the definition set it had. I noticed there is a Check for Updates button, so I clicked it thinking it would check and notify me if updates were available.

    Well, it automatically downloaded the latest Definitions without warning. All is good though, as everything went smoothly, including the Quick Scan. As an added benefit, the Windows Update notice also went away; it was smart enough to know WD was updated.

    Thanks for all the help!! :)

    Hi,
    If you want to use the slowest scanner ever created feel free :)
    Be aware WD often needs to do a full scan not quick.

    I also use Malwarebytes free, and occasionally HiJack This. I've never ran a full scan with WD but I'd imagine that with approximately 4.8TB worth of files in this box it would take all day to run. I also never looked to see if I can exclude things like my photo and home movie drives, but I'd imagine there's a way.

    Or should I run it on C: drive only...??


    What scanners do you use/recommend?
