Well, if the registration process with the newest version of Avast is as simple as it seems right now, then that will be fine. I did not know if it would later revert to it's complicated past when it comes time to renew in one year. It's complicated past being that on previous versions you had to enter your email, and then they would send you a product key through your email that you had to enter to activate the product. Again, easy for you and I, not so much for some of our clients. In the past, with Advast, our clients would ignore the request to re-register, which is why we started using AVG.
Seriously, the free version of AVG (like AVG 8.0, 8.5, 9.0) did not require registration. You just installed it, configured it, and sent it on it's way.
But back to Avast, it that's all there is to it, then fine.
