it is a belief, albeit non-orthodox, related the the Unholy Trinity.. people take it a little more literal than the original scripture did and thus made the Unholy Spirit.. it's a bit heretical if you follow the original texts (since the Holy Spirit is the most respected of all the Trinity) but the concept is explored in fringe groups / occult etc..

in fairness it could just be merged with Anti-Christ, as it's pretty much the same deal.
