Error- AAVM initialization error aavm start avworkinitialize failed ooooA413.
RPC error is generally related to other antivirus present or, at least, firewall blocking. RPC error may also be because of avast! services being stopped. Anyway, RPC error is most likely correct by repairing avast! installation
Also, take a look into Administrative Tools > Services
and see how the four avast services are set to start (automatically or manual).
