Solution: Allow Logos through Antivirus Software

This problem may affect Logos 4 and 5 and can occur when any antivirus application attempts to delete or quarantine Logos files as a potential threat. The result is an incomplete Logos installation and cannot be repaired until Logos has been allowed through the antivirus application. Once an exception is created, you will also need to repair Logos.

    Step 1: Allowing Logos
  • Open your antivirus or security application.
  • Location the Options or Settings menu.
  • Look for an option for "Exceptions" or "Allowed Programs".
  • Add the Logos directory to the list:
    C:\Users\User Name\AppData\Local\Logos5
    Note: "Appdata" is a hidden folder and may not be visible by default.
  • You may also need to add Logos.exe (or Logos4.exe).
    Step 2: Repairing Logos
  • Go to "Start".
  • Open the Control Panel.
  • Select "Programs and Features".
  • Right-click on "Logos Bible Software".
  • Choose "Repair".

These steps should resolve the issue and Logos will open. Note, the steps above are generic; the exact steps may vary by application brand and version. If you have any difficulty following these steps, please contact your antivirus or security vendor for further assistance.

Is Logos a threat?

At Logos, we take extensive steps to ensure security for Logos users and maintain a clean application. It is highly unlikely that Logos contains an actual threat, but occasionally some antivirus and security vendors may flag a Logos component by mistake. As long as you are downloading Logos from or an Official Logos email, you should not need to be concerned.
