Please do run McAfee Virtual Technician using below steps and check if the status of the issue. If the issue persists, please do reinstall McAfee.

  1. To start, go to the McAfee Consumer Support home page, and scroll down to the McAfee Virtual Technician section:
    NOTE: The Virtual Technician is only available on Windows PCs. You do not see this option if you view this page on a Mac, or an iOS or Android device.

  2. Click Download and Run.
  3. Save the mvt.exe file to your desktop if prompted.
  4. Double-click mvt.exe, or click Run, to start MVT.
  5. Click Yes if the Windows User Account Control asks you to allow MVT to run.
  6. Wait for MVT to install, initialize, and update. This process might take a few minutes.

    MVT then scans your PC for issues with your McAfee product.
  7. If any issues are found:
    1. Choose Autofix, and follow the prompts to let MVT fix the problem.
    2. If MVT cannot fix the problem, contact Technical Support.
  8. If no issues are found, close MVT.
