It says this is the affected item when quarantined "amsi\harddiskvolume5(Zayden)\downloads\tcblaunch.exe" and im very confused because i dont understand why tcblaunch.exe is being found in downloads, i think it is a trojan, and i need help. Edit: i forgot to mention that it disappears from virus and threat protection after a few minutes/seconds and i did an offline scan and found nothing

    Please share your Farbar scan logs for analysis.

    • Download Farbar Recovery Scan Tool 64-bit FRST64.exe
    • If the OS language is not English, rename FRST64.exe to FRST64English.exe.
    • Run the program. Don't check or uncheck any options. Click "Scan".
    • Add the two logs, FRST.txt and Addition.txt, to a zip archive.
    • Share the zip file on OneDrive or GoFile.io, and post the link here.

    Note: If Microsoft Edge or Chrome mislabels the Farbar Scanner executable as PUA/malware, choose to keep it by tapping … in the bottom bar, choosing Keep, and then choosing Keep anyway in the dialog that appears. See this screenshot. It's a safe tool used in most antimalware forums.

    tcblaunch.exe is a real Windows component, the “Trusted Computing Base launcher.” It’s part of the secure-boot and virtualization security features (Secure Launch / VBS). The genuine copy lives in C:\Windows\System32, and Windows never puts it in Downloads. May be something you downloaded or ran put it there.

    Don’t restore or run the file. If it’s still in Protection history, open the entry and note the threat name (e.g. Trojan:Win32/...) and the date and time.

    Look in Downloads for the archive, installer, or tool that came with it, especially cracked software, game mods or cheats, “driver fixers”, or anything from Discord or YouTube links. Delete it.

    Run a second opinion scan, such as Malwarebytes Free or Microsoft Safety Scanner.

    Check persistence. Open Task Manager, then Startup apps, and look for anything unfamiliar. Also open Task Scheduler and look for odd tasks. Run autoruns from Microsoft Sysinternals if you’re comfortable with it.

    If you actually ran something from that download, change your important passwords (email, banking, Microsoft account) from a different, clean device, and turn on two-factor authentication.

    If anything still seems off, such as unexpected processes, disabled security settings, or new startup entries, back up your personal files and consider resetting Windows with “Remove everything.”
