I'm currently at v6.0.1000 Free having updated via AvastGUI from 5.1.889 when V6 became available. All is working well, with the Avast install remaining in C:\Program Files\Alwil Software\Avast5. Would there be any advantage to a clean install so as to have the more generic install path so future Avast versions have less problems with it's housekeeping?
