I'm running the latest OSX version in 10.6
I know avast! is currently broken with 10.6. Any news of a beta ?! or update soon. I've been trying to forget the persistent loading of it but it's really getting on my nerves now! 
Yes, beta with automatic incremental updates of both VPS & engine and some enhancements is working OK on my computer and would be ready for public in few days (I hope). Unfortunately, last build had problems on old good 10.4 (modification for 10.6's side-effect). Ah, that Apple's compatibility.
this is apple's style in a nutshell:
1) tell to all that this is the standard
2) change it
3) goto 1
