We can manually remove it. Please provide Farbar Recovery Scan Tool (FRST) logs for analysis.

Note: If you are using Edge or Chrome, SmartScreen may initially block the download. Click on the three dots next to the warning and select Keep => Click the Delete drop arrow => Keep anyway.

  • If your computer's language is not English, rename FRST64.exe to FRST64English.exe
  • Run the tool, leave the default settings, and press Scan.
  • Zip the logs, FRST.txt and Addition.txt, then upload to a cloud storage service like OneDrive, Google Drive or gofile.io
  • Post the share link.

    • Save Fixlist.txt to your Downloads folder.
    • Close any apps with unsaved work.
    • Run FRST64.exe and click "Fix".
    • The computer will reboot to complete the procedure.

    Please upload Fixlog.txt so I can check if any further action is needed.

    Why your AV scans aren't catching it

    • Signature-based scanners look for known malicious files. If the actual payload is injected in-memory via MSBuild rather than sitting on disk, there's nothing for a normal scan to flag.
    • Malwarebytes caught this because it monitors network behavior, not just files — which is exactly the right layer to catch this.

    What to do

    1. Don't click "Allow website." Leave it blocked.
    2. Find what's invoking MSBuild. Malware rarely calls MSBuild directly — something else launches it. Check:
      • Task Scheduler (taskschd.msc) for suspicious scheduled tasks
        • Startup apps (Task Manager → Startup)
          • Recently installed programs, especially anything downloaded from cracked software/game sites (the domain name pattern strongly suggests piracy/keygen-site origin)
          1. Run Malwarebytes' full scan (not just real-time protection) — Scan → Advanced scanners → include rootkit scan.
          2. Try a second-opinion scanner that specializes in this: ESET Online Scanner or Kaspersky Virus Removal Tool, both free, both good at catching LOLBin abuse.
          3. Check for a malicious .csproj or .xml file that MSBuild might be pointed at — search for recently modified .xml/.csproj files in Temp, AppData, or Downloads.
          4. If you can, boot into Safe Mode and scan there — this stops the malware process from actively running/hiding.
    3. If you recently downloaded pirated software, a game crack, or a keygen, that's very likely the entry point — worth mentioning if you want more targeted advice.
