Hoping this is the correct thread, I can't seem to get a response when I attempt to register the Avast 4.6 Home Product for the first time. I have checked filtered mail at my ISP. I've checked my local rules filters and "deleted" file. I don't reject overseas mail. Any hints? I can obviously connect to your web site, and the installation seems fine (you even found a virus in a "deleted" Outlook folder I had archived years ago - good work, as well as detected that I had tried Panda, which fails to hide its virus signatures!).
