From the avastUI > Settings > Antivirus - scroll down to Hardened Mode and enable it - Moderate setting is what many would go for (I did), but it appears to be somewhat more noisy than the Aggressive setting.
See RejZoR’s description on the effects of and use of the avast! Hardened Mode - http://forum.avast.com/index.php?topic=142172.msg1032485#msg1032485.
