If it keeps coming back, there is likely to be an undetected or hidden element to the infection that restores or downloads the file again, at least avast is stopping it when it is restored.

What is your firewall ?

If you haven’t already got this software (freeware), download, install, update and run it, preferably in safe mode and report the findings (it should product a log file).
