I have been evaluating SpywareBlaster 3.1 and generally like what it offers. I am now considering purchasing an auto-update subscription, but have some pre-sales questions first: 1. Does the subscription apply to a single machine only? 2. I run a small company network: what licensing arrangements are available to us? 3. The subscription order process requires a machine ID. I presume this means that a subscription is valid for a single machine, but ... a. What hardware (and software) changes would invalidate the machine ID? b. How would we obtain a replacement licence key when replacing a machine? c. Would there be any costs associated with this?
