I am using Avast! home (free) for my virtual PC, but using NAV 11 for my Mac protection. I am waiting for an updated version of Avast! with similar functionality to the PC version before I purchase it. I have purchased and preordered too many things in the past to purchase something until it is available.

The thing that bothers me about avast for the Mac is that I feel like I paid my money to be a Beta tester. Half a year later and users are still trying to figure out work-arounds with no updates in sight. That is very lame!
Well Avast for Mac is most likely handled by the same development staff that does the Linux/Unix Versions, so their time is split between different development projects. Due to the Smaller Market Share of Mac/Unix/Linux it would not make sense business wise to have a separate development team for each of them.
At least thats my theory for the long wait times for the Mac and Linux Versions 
Hallo,
the original idea (= incremental update of virus database) evolved in April into full-incremental setup of the whole program (with the update machinery nearly the same as in Windows). Integrating such windows-tied mechanism to Mac while keeping all the necessary per-user separation, no-need-for-reboot, fail-robustness etc., necessary for the "unix-like" port is a bit time consuming. Testing is even more painful (for your imagination, preparation of one testing round takes 5hr (G5) - and for whole testing you need at least 2 subsequent rounds, etc., and after each change in the binaries the hierarchy must be re-built).
I really don't understand why people expect the Mac version to look/work exactly in the same manner as the Windows avast! - the differences between Unix/Windows simply don't allow many things that are common in the world of Windows - simply because of user-separation principle. Such antivirus would look nicely, but could be also misused as "nice" security hole (user->root privilege escalation etc.).
The low-level parts of local and server-side incremental update mechanism are finished, some changes in the GUI were made before, so now it's time to put it together as the next version.
