If your last update (virus definitions) is 9/18/2013 then you have a larger problem than the streaming updates. As that is 16 days old.
What happens when you try a manual virus definitions update, e.g. are you getting any errors ?
You could also try a Manual update of VPS - avast! Virus Definitions Update - Manual Download VPS Update (virus definitions, vpsupd.exe, approx 103 MB). - Save the file to your hard disk, locate where you saved it and double click it and that should carry out the virus definitions update.
If that doesn’t resolve it then you are probably looking at a clean reinstall.
