Quarantine

Hello, Warren.
May I know if it is on Windows or Mac device that you are trying to clear the files from Quarantine? Please let me know the exact error message if it generates any when you try to delete the files.
For your information, Quarantine isolates such files from the rest of your operating system, and prevents the files from being accessed or run by any outside process, software applications, or viruses.
Thank you for the detailed information.

Please check whether you have correct permissions on the below folder

"/library/Application Support/AVGAntivirus/config/chest-data". "System" should have "Read & Write" privilege.

If it set correctly, please let us know and we will assist you further.
