I think so, as the weird error message related to a successful completion and there were no unpxxxx.tmp files remaining, which only usually happens with a failure of some sort; allied with no avast error displayed and the images being loaded.
Personally I don't go looking in the avast log viewer (unless there is a problem) as the stuff in there is verbose (and looks scary) and more use to the programmers in certain sections of the log viewer. It gets more so the lower you set the program settings, logging, mine is set at Notice (default) so everything above that is logged. If set to Info or Debug more is logged and also recorded in the windows Event Log, anti-virus.
