    Windows Defender History

    Just a little while ago Defender reported it detected something severe.
    I should have noted the file and location, but in my haste I did not.
    I asked Defender to remove the offending file.
    When I saw it classed it as severe I just started running scans.

    Malwarebytes (free edition), and a Windows quick scan found nothing.
    A few minutes later same thing. This time I downloaded the latest MS Security Scanner It found nada.
    I was hoping there was a history log so could look back at what the file name and location was, but cannot find any place to view that.
    I did follow Brink's method of going to view protection, but it shows no recent actions, and I do not see any filter option on my screen to open a log file.

    Any thoughts ?

    Windows Defender, view the log at C:\ProgramData\Microsoft\Windows Defender\Support

    MS Safety Scanner, view the log at %SYSTEMROOT%\debug\msert.log.

    Jmatt first thanks for responding.

    I looked at the first item you posted, and I will admit that's quite a log that I did not completely understand all that was transpiring.
    Knowing the date I managed to scroll down to that area. I noticed "all sorts of commotion" going on and tried to decipher.
    The problem looks like it was a trojan:html/!

    I could see references to 2 different times that windows had issues with at least 4 different .jpg files that were first quarantined then next removed. That agrees with the 2 different times that I saw the screen notice pop up.

    Each day I look at quite a few E-Bay photos for purchasing reasons, and I'm thinking maybe a trojan could hitch a ride to my computer via that route ?
    Since then running as many scans as I could think of it's all clear, however I'm going to do a full system scan just to be sure.

    It was quite interesting to see the Windows 10 resources mobilized to get hold of the problem(s)

    Thanks again for the information

    Hello @smalltown,

    Just in case you wanted to output the current Quarantined Items to a Desktop file, type [ Or Copy & Paste ] this command in a CMD Prompt and press <Enter> . . .

    "%ProgramFiles%\Windows Defender\MpCmdRun.exe" -Restore -ListAll > %UserProfile%\Desktop\Defend_Q.log

    It will output a Defend_Q.log on the Desktop.

    I hope this helps.

    "I'm going to do a full system scan just to be sure."
    I would also run this.

    Run ESET Online Scanner. Copy and Paste the contents of the log in your reply please. This scan may take a very long while, so please be patient. Maybe start it before going to work or bed.

    jmatt I Downloaded and installed the ESET program. I did not see any advanced options. Maybe you are using a paid version?
    That said I ran the program, and ticked that it should remove any problems it found. It did indicate that it has issues with three items.
    Tried to attach the file, but the screen only shows me the files I had previously uploaded so I cut and pasted.
