should both boxes be ticked? The bottom one is ticked on my computer but both are on my husband’s. Neither of us changed the settings.
Only the bottom one.

Thanks. 
Someone changed the settings as the default if for Silent/Gaming Mode is off (unchecked) by default.
If at any time you are confused if settings have been changed you can restore the default settings, avastUI, Settings, Troubleshooting, Restore Factory Defaults.
Okay…I’ll change to the default settings.
