What are stx.dll Error Messages?


Dynamic Link Library stx.dll Errors

stx.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like stx.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. 360 Total Security) could share the same stx.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when stx.dll is attempted to be loaded either when 360 Total Security is starting up, or in some cases already running. Some of the most common stx.dll errors include:

Your stx.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with 360 Total Security), or deleted by a malware infection. Furthermore, stx.dll file corruption could be caused from a power outage when loading 360 Total Security, system crash while loading stx.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

How to Fix stx.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your stx.dll issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. When you see the search box, type "System Restore" and press "ENTER".
  3. In the search results, find and click System Restore.
  4. Please enter the administrator password (if applicable / prompted).
  5. Follow the steps in the System Restore Wizard to choose a relevant restore point.
  6. Restore your computer to that backup image.

If the Step 1 fails to resolve the stx.dll error, please proceed to the Step 2 below.

Step 2: If recently installed 360 Total Security (or related software), uninstall then try reinstalling 360 Total Security software.

You can uninstall 360 Total Security software by following these instructions (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button
  2. In the search box, type "Uninstall" and press "ENTER".

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many stx.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the stx.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.

CAUTION : We strongly advise against downloading and copying stx.dll to your appropriate Windows system directory. Qihoo 360 Technology typically does not release 360 Total Security DLL files for download because they are bundled together inside of a software installer.
