It's annoying that whenever there is a new version, if one chooses to get it, old version gets erased, it should at least be renamed as adwcleaner.bak in case downloading of newer version fails (or doesn't work in winxp anymore as it happen to be my case). So now I don't have either version.
Which brings me to another topic: Where is it possible to DL older versions so I can recover this great utility?
