    Hi mknic,
    I have literally just installed the definition update KB2267602 without any problem. I suggest as a first step checking all the Windows Defender settings to make sure they all have the 'green ticks' in each section.

    ps. The only reason the 'Family Options' is not ticked is because I am the only user on my computer.

    I also would suggest running the 'Troubleshoot' feature in the Update & Security settings which has a section dealing with update problems.

    Hi mknic,
    To be honest, I have never been a fan of McAfee, and whenever I have purchased a new computer with McAfee / or Norton pre-installed on it (which is almost always only a 6 month subscription), the first thing I do is remove it and replace it with a good free antivirus....and there are some very good ones out there that out perform some of the (paid-for) variety. As to whether or not McAfee has caused this issue with Windows Defender, I somehow doubt it, but having said that.....some AV's do not like/allow other AV's being present on a computer and will 'disable' them.
    I personally use a SecureAPlus Premium which I got as a 'givaway' with a 'lifetime licence' with free updates.
    SecureAPlus uses 11 other very well known AV's (including McAfee) to scan for threats. It also automatically runs a 'background scan' whenever you boot up your computer on a daily basis.
    Did you run the troubleshooter, and if so what was the result ?
    Microsoft recommends running the troubleshooter for problems with Windows Defender.
    I have myself just updated Windows Defender and noticed the last 50 updates are all marked as KB2267602, but with different 'definition' numbers.....the latest being KB2267602 (Definition 1.277.997.0)
    There are guys/gals here on tenforums who are retired IT Professionals that may be able to offer further help with your issue.
    One word of advice (based on experience)....supply as much precise information as you possibly can to them including screenshots (if necessary) in order for them to be able to assist you.

    Quick way to find out....disable McAfee, and check for updates.

    Using the command prompt, try the following inside the Windows Defender folder:
    MpCmdRun.exe -signatureupdate -MMPC

    The key parameter is the MMPC, which in my case eliminates the errors. Not wanting WD to miss any updates, I have created a batch file and have Task Scheduler run it twice daily.
    cd c:\Program Files\Windows Defender\
    MpCmdRun.exe -signatureupdate -MMPC

    Great!

    I don't usually have a lot of faith in MS tools, but it's worked whenever I've needed it.

    @hello10,

    The folder you are using contains an older version of MpCmdRun.exe.

    The latest version is in the latest folder within C:\ProgramData\Microsoft\Windows Defender\Platform

    When this change happened [sometime last year, I think] I altered my batch file in order to ensure that it will always use the latest version:-

    Code:
    set GetLatestVersionPath="dir "C:\ProgramData\Microsoft\Windows Defender\Platform" /ad /od /b"
    FOR /F "tokens=*" %%i IN (' %GetLatestVersionPath% ') Do Set LatestVersionPath=%%i
    "C:\ProgramData\Microsoft\Windows Defender\Platform\%LatestVersionPath%\MpCmdRun.exe" -SignatureUpdate

    The For command examines each entry in the (set) and sets the path for each entry but the fact that the (set) is sequenced in date order means that the For command will always end up setting the path to the latest version.

    Thanks for the info. I hadn't known there's another set inside ProgramData.

    [Update]

    I tried your batch. Now, when I go inside the Virus & threat protection updates, unlike before, the page shows an empty Threat definition version, Version created on, and Last update. Only when I click on the Check for updates button do the corresponding info come out. I don't know if running your script has anything to do with this. I tried rebooting, and got the same.
