I regret to say that the old version of the web site was far better than this one, in which I did not find what the last vps version is. And also, there are no release notes about the latest version of the anti virus itself - e. g. what is the difference between avast! 5.0.377 and version 5.0.396.
Thanks for reading and commenting.
the new website have only been there for 10min so give it some time and the info will be there
