Thanks for the reply. I suppose I can do it that way (with the 30-day money back guarantee). It's just annoying because if it won't work with Sophos it's no good to me, and with a money-back guarantee I have to carefully read the T&Cs, instead of just installing the trial and checking it works. I still haven't figured out how to install the 'free' version of KSK, apparently there is some free version with limited features (according to some reviews), but I created an account and can't see any option to download software without a subscription.
