Presumably this is related to webmail ?
If you don’t want to install the mail shield to remove them I’m afraid you are stuck with them as currently there is no option in the Web Shield to do this for webmail.
This problem has been answered by one of the avast team here https://forum.avast.com/index.php?topic=178976.msg1266788#msg1266788
On a later program update it is intended to replicate this option on both web and mail shields, when this is likely as an avast user like yourself I don’t know.
