Windows 10: Unknown User accounts appearing (malware related??)

    Unknown User accounts appearing (malware related??)

    Today I discovered strange account names on my laptop after trying to open files on one of my drives which also had strange names and were not mine. I suspect my laptop is infected with some kind of malware but unfortunately all scans (malwarebytes, f-secure, hitmanpro,..)do not flag up a specific threat.
    I attach a printscreen:

    The above two windows indicate the useraccounts (see top two) with content of one of them (top right). The down-left window indicates the files I tried to open and which may have installed some malware an created these accounts (not sure however if they were there already before).

    Furthermore each time I try to delete the random named folders-files on drive D (bottom left window of the printscreen), they re-appear with different names...

    I did not try to remove the useer accounts yet and have no idea how I safely could.
    Please help.
    Kind regards

    Welcome to the TenForums @Stef0099

    Any chance you are using Eset security and have AntiTheft enabled?

    Unknown User Account - ESET Smart Security & ESET Internet Security - ESET Security Forum

    You might have another anti theft product that does something similar.

    If you think it is a virus have the thread moved that section.

    Thanks for the reply Ken.
    I am not using Eset but I did install a number of weeks ago Cybereason Ransomfree...Could this program be doing this?

    Could be... is the cyberreason anti-ransomware that you have installed
    That creates dummy files in various locations on your computer and constantly monitors them, so if a ransomware "virus/Trojan" does get on the computer, it is supposed to stop it while it is encrypting the dummy files, supposedly before it attacks your files...
