Sorry I forgot to get back. They sent me the key and instructions within a week. No reply weather or not they would support the 10 licence family pack again. As advised below I am sticking with 4.8
If you wish to upgrade any of your workstations to V5, be aware the you will loss the ability to manage it by WHS.
V5 is NOT currently compatible with the avast! 4WHS Edition. The current range of V5 products is designed for individual workstations only.
We are looking at upgrading the current avast! product range to V5, but this will take some time.
For the moment, customers who use the WHS should stay with V4.8. We will continue to support our customers with all necessary updates.
We will let you know when the V5 upgrades will be launched.
If you wish to upgrade your workstation, first, please uninstall V4.8 Avast Antivirus, reboot computer and install fresh copy of V5.
