Could you indicate which option to choose from the avast folder to add the path on the firefox’s addon?

Thank you in advance

This is it - C:\Program Files\AVAST Software\Avast\ashQuick.exe.

Though the Web Shield should be scanning executable downloads anyway.

Oh namely it would be exaggerating a setting like this! OK thumbs up…
