Two points. 1. How am I supposed to know which version of AdAware (free version) I have? - there's no obvious indicator that I can see on the splash screen. 2. AdAware has just deleted my Outlook .pst file. It was only AFTER this happened that I have seen suggestions that you exclude this file from the scan, Therefore either make this risk clear on installation or get the .pst excluded by default or get it backed up to somewhere obvious where it can be recovered if neccessary. If you want to know how and why this happened I can provide more info.
