I’m just wondering when version 8 of the client will be available for business customers.
I have recently updated some home versions and am really liking the new interface - especially the added features (mainly the Software Update) and am anxious to be able to roll this out at the office.
I am wondering the same thing. How do we update?
If you look at the release history for the home products http://www.avast.com/en-us/release-history versus business clients http://www.avast.com/en-us/release-history-business you will see there is not yet a version 8 for business 
The business line will get a update soon but it may not be v8. The business line has traditional been a every other release type schedule. They focus on product stability instead of rapid releases like the consumer line.
