The very first thing one should check in case of Total AV not working issue is to-
• Check the internet connection as this antivirus requires to be run on the updated version

• If the user has an old version then, they won’t
be able to use TotalAV
• Install all the available updates and if it still is not working then, reinstall the software
There might be an issue that any of the setup files has been corrupted. Contact Total AV customer care UK for complete assistance.
