Q1: Please Choose Your Sophos Product:

Antivirus Update Error

An antivirus update error may arise while running application control and Sophos antivirus. The antivirus update error in Sophos denotes the inability of the software to download and install the latest virus definition updates or program updates. Antivirus updates are important to ensure that the Sophos software provides the most updated protection against upcoming threats.


  • Application Control blocking files that are necessary for Update
  • Internet connectivity issues 
  • Another software conflicting with Sophos
  • Software or system compatibility issues 
  • Blocked by the firewall or security settings 
  • Corrupted or missing files


To resolve the update error, you will have to adjust some settings. Follow the instructions below.

Solution 1: Verify your internet connection

The first step to troubleshoot the update error is to check your internet connection. An unstable internet connection or network issues can stop antivirus software from updating properly. You can restart your router or connect the device to a different network.

Solution 2: Restart your Sophos services

Restarting your Sophos services can help you resolve the update issues. In order to restart them, follow these steps.

  • Press the Windows and R keys together and type services.msc to open the Services Manager on your computer. 
  • Locate the services starting with Sophos. 
  • Now right-click on the Sophos services and select Restart and wait for it to restart.

Solution 3: Check for the conflicting software

You have to check there is no other antivirus or security software installed on your computer that is interfering with Sophos. More than one antivirus software may cause conflicts. Hence, if there is another security software installed, it’s better to uninstall it and then update Sophos again.

Solution 4: Delete temporary files

Certain temporary files may help you resolve some update errors. To delete the temporary files, follow these steps.

  1. Press the Windows and R keys together to open the run command.
  2. Then, type %temp% and click Enter. It will open up a temporary file folder. 
  3. Now, select all the files and folders in the temporary files folder and press Shift + Delete to delete the temporary files completely.

Solution 5: Manually update Sophos

  1. Move to the Sophos website and log in to your account. 
  2. Then, go to the Downloads section and find the latest update package for your Sophos product. 
  3. Now, download that updated package to your computer. 
  4. Launch your Sophos software and locate an option to update the package manually.
