    Just found this via Defender full scan - TrojanDownloader:O97M/Obfus.MK!MSR


    Hey everyone, I'm pretty decent about keeping things up to date and let Defender manage all things A/V related but for some reason a trojan got thru via some excel files I was sharing with my boss. I didn't find it until I did the full scan and running a search on Microsoft's site showed that it was ID'd 3 years ago. Before this happened I did a full re-load of windows, deleting all files and resetting everything. I keep the machine behind a Mozilla VPN when I'm not on home net and the only thing out of place after restart and walk-through with setting everything up was a loss in bei

    Trojandownloader: O97M/adnel

    Hi,

    I used the Microsoft Malicious Software Removal Tool to scan my computer. The scan results show Trojandownloader O97M/adnel as malicious software detected but not removed.

    The Microsoft Malicious Software Removal Tool did not remove this trojan file. I dont know why.

    How do I remove this malicious software?

    Thanks

    <Moved from Windows 10>

    Hi Ian,

    Thanks for posting your query on Microsoft Community.

    This issue might occur if you have set any task scheduler for Windows Defender.

    I suggest you to delete the task for Windows defender and check if it helps.

    Follow the below steps:


    • Search and open Schedule tasks.

    • In the left-hand menu, open the Task Scheduler Library, then select
      Microsoft >Windows >Windows Defender.

    • Double-click Windows Defender Scheduled Scan.

    • Select the Triggers panel, then select Delete.

    Hope it helps, reply to us with the status of your issue. We will be happy to assist you.

    System Requirements

    Microsoft Safety Scanner Download - Windows security

    Sometimes you have to try two (2) times to click in the links, other wise you can get the “We aяe sorry, the page you requəsted cannot be found.”

    The Microsoft Safety Scanner is NOT supported in Win10.

    First, verify that the time, date/year & time-zone are set correctly

    <<http://goo.gl/ElJr9v>> Win 10

    Reboot if you changed any of the above.

    Clear up your Temp File/Cache.

    Clean up the system (clearing out all the temp/tmp folders, and included all offline content, clearing the browser tif, delete cookies, etc. etc..


    (Important:One of the normal steps in eliminating malicious programs is to entirely delete the contents of all Temp folders.

    <<https://wiki.umbc.edu/pages/viewpage.action?pageId=1867904>>

    Best and easier to use - CCleaner.

    Download the basic (slim) (Free Download) build via

    <<http://www.piriform.com/ccleaner/builds>>

    The basic (slim) build does not contain the disgusted Toolbar, the standard build installs the Yahoo Toolbar as an option which ischeckmarked by default during the installation. IF you doNOT
    want it, removethe checkmark when provided with the option
    ORdownload the toolbarfree Basic SLIM versioninst
    əad.)


    DO NOT USE ANY Advanced cleaning options.

    DO NOT TOUCH THE REGISTRY. At least not for now.

    Reboot.

    `~`

    Follow the links and download the tools scanning with each then reboot aftər each scan.

    These can be done in Safe Mode - repeatedly tap F8 as you boot however you should also run them in regular Windows when you can.

    1. -Please download and install Malwarebytes (MBAM)(), update definitions and run in normal mode. Disable othər security software whilst you are doing scans.

    <<https://www.malwarebytes.org/antimalware/>>

    Pləase make certain you uncheck the box beforeEnable free trial of Malwarəbytes Anti-Malware Premium.

    <<http://goo.gl/0TkcEN>>

    Make sure in Malwarəbytes the
    Scan for rootkits box is checked-> Settings-Detection and Protection.

    `~`

    The recommendation is to use the intelligent quick scan routinely, and do full scans either on a longer periodicity--weekly, monthly--or only when something is found or you have some rəason for suspicion.

    `~`

    2.- -Run SUPERAntiSpyware (SAS) Online Safe Scan,Same as above.

    3.-RunAdwCleaner

    4.- Run Junkware Removal Tool


    <<http://www.bleepingcomputer.com/download/junkware-removal-tool/>>

    `~`

    5.- - And finally, download and run ESETOnline
    (One-Time) Scanner.
