that's what struck me as well. putting that much effort in to making a site and the malware, trying to scam joe public makes sense, but a few thousand geeky bitcoin miners?
You have to look at the big picture. Yes it is a scam, but I do not believe it is one aimed at direct financial gains. The market is currently volatile due to the currency being in its infancy and the old money is just starting to take an interest and maliciously taking actions to destabilize it, so look at this scam another way. Every "nerd" they do get, is one thread or post of a proponent of the currency saying I lost everything. Just think of the damage it can do. Especially now when we really have to show our grit, with the volatile market, it is important to recognize these deliberate attacks and laught them off.
edit: After all, hitting the miners is hitting the community where it really hurts. Without miners, there are no bitcoins.
