Thing is Asyn, there's ten months left on this license and I'm not prepared to throw that away. I'm happy to continue using any version of Avast, I just want to get it functioning properly.
Yesterday, after I reinstalled the version I had bought, it updated itself to v8.0.1483, and this morning there wasn't any free version to be found listed in my program files so I'm wondering if the problem might have been solved by using uninstall tool, which might have cleaned out any residual files from my earlier free version. Dunno!
