Dlusb-c120.exe [exclusive]

I cannot draft an article about the file dlusb-c120.exe because there is no verifiable, legitimate, or widely recognized software component associated with that name in any reputable software database (e.g., Microsoft, Dell, HP, Intel, or common driver repositories).

Here’s why you should be extremely cautious:

  • Unrecognized filename pattern – The dlusb prefix might superficially resemble DLL or USB driver naming conventions, but no known hardware manufacturer (like FTDI, Silicon Labs, or Prolific) uses this exact filename.
  • High risk of malware – Many trojans, keyloggers, and ransomware executables use random or obscure names to avoid detection. A .exe with an unfamiliar name running on your system could indicate infection.
  • Missing digital signatures – Legitimate USB drivers are almost always signed by a trusted certificate authority. Unless you obtained this file directly from a verified source, treat it as suspicious.

How to remove or quarantine safely

  1. Unplug the device (if the file is linked to an attached USB device).
  2. Create a restore point (System Restore) or a full backup.
  3. Uninstall related software via Settings → Apps or Control Panel → Programs and Features.
  4. Use an antimalware tool to quarantine/remove if flagged malicious.
  5. Manual removal (advanced)
    • Reboot to Safe Mode.
    • Terminate the process in Task Manager or Process Explorer.
    • Delete the file and related driver entries (Device Manager → uninstall device, delete driver).
    • Clean leftover registry keys only if comfortable; otherwise use a cleanup tool.
  6. Reinstall official drivers from the vendor site if you need the device working again.
