Awake from all you’ve said I’m pretty sure you are (and were) NOT infected by anything - it was just a file in a temp folder, really nothing to worry about.
SpeedyPC, you should be able to update to 418 from any previous version. But – if you used any of the betas, please revert the servers.def to the original [release] version (can be download here: http://www.avast.com/iavs4x/servers.def ).
Thanks
