    'Musecador' backdoor was detected


    We have received 'Musecador' backdoor was detected alert on Defender for about 35 user machines. When Investigated further on this alert, PreSignInSettingsConfig.json detected as Backdoor:BAT/Musecador.A by Windows Defender, generated by OneDriveStandaloneUpdater.exe and a VirusTotal detection ratio: 1/68 according to Microsoft Defender ATP but when checking this manually at virustotal.com the detection rate is 0, false alert in the definition files?


    Current OneDrive version is 19.172.0902.0013

    calc.exe Calculator worms IRCBot backdoor Trojans

    Lynn,

    Are you saying Defender detects Microsoft's own calculator as an IRC backdoor Trojan?? That seems unlikely, really. It detects it, then what? That worm is very old and risk level is rated Low by Symantec.

    Windows phone is not detecting

    Hi Vijay,

    Thank you for posting your query in Microsoft Community.

    I suggest you to connect the phone to another computer and check if it gets detected. Also, check if the phone gets detected by connecting with a different USB cable.

    I suggest you to run the Hardware and Devices troubleshooter by following the steps below:

    • Click on the Start button, and type “Troubleshooting” on the search bar.
    • Click on “hardware and devices”.
    • A pop-up will appear, click on the “Next” button and follow the on-screen prompts for troubleshooting.

    Hope the information is helpful. Keep us posted on the status for further assistance.
