Lunch sounds good but it'll have to be on the weekend. (Too much stuff I have to get done here at college during the week)

Version 4.0.168 was released back in February. There have been several versions since then (4.0.172, 4.0.183, 4.0.202). I think it's time for an update.

Right click on the blue avast tray icon, select Updating, then click on Program Update & it should DL & install all the files it needs. You might want click on iAVS Update & update your virus database too.
From the simple user interface, under Settings, Update, what circles do you have ticked? I've got DSL so I have mine set to Automatic.
