sorry, haven't heard of either, if you left a link or something.
do a cleansing, basically have a bath with sea salt. sit and breath deeply, as you pour the water over you [don't have a bath, like soap and shampoo] visualize a white light and the water in the tub growing black. then carry around a charm or a crystal for protection. i'd move up from their, like a protection spell on your and your house, and cleansing the house and so on, but i don't know the spells, so i can't help with them, sorry.
