    Defender keeps finding the same "Trojan downloader"


    For the past week Defender has been going off for a TrojanDownloader:O97M/Donoff or TrojanDownloader:O97M/Dornoe.C!ams. I'm not sure how to stop this happening, I don't download random email attachments or anything like that but the description of it seems to suggest that's how it's executed. Malwarebytes isn't finding anything else besides PUPs.

    The location always seems to be in a similar area in AppData:
    PHP Code: C:\Users\Craig\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Files\S0\75\Facture_Num_J691534[673].doc
    Not sure what to do with this one. I feel like it might be a false positive, but then I don't know where the docs are coming from.

    :)

    Defender locates trojan win32/Dynamer!ac but cant remove it

    Bruce,

    Thanks for the link. When I run step 1, tdsskiller it does not find the trojan. It looks like this progam is only scanning disk c, defender is locating the trojan on disk d.

    Any ideas?

    Thanks again.
