Martin, check my post https://forum.avast.com/index.php?topic=172345.msg1230189#msg1230189, whilst I can’t reproduce the error of gtx66 - I do have an anomaly.

Where the image attached in my post link above shows (from running a Smart Scan) that my PC performance has been optimized, now presumably that would mean that cleanup has run (?) yet there is no cleanup entry in the avastUI > Settings > Tools.
