The only one I would recommend (and I don't know every single one that exists) is Farbar.
But the fixlist should be only created by someone who has the relevant knowledge about both how Farbar is working, what options it has etc as well as being able to find the correct information about entries that are unknown to that person.
In my opinion there is absolutely no need for avast to add something like this to the av (or other tools).
avast already does detect things and it is just a matter of adding more/better detection either in the VPS or "rule based" detection as well as better removal for things that are detected.
e.g. not only remove the malicious file(s), but also all corresponding registry entries.
p.s. Was the swimming pool in their hq ready?
