Black Magic and Negative Forces.Varaha Kavacha, Sri Mantra Rajapadam are quite powerful.There are also Mantras in Soundraya Lahari which would provide relief.

Ihave come across A Siva Mantra ,called Amogha Siva Kavacham , addressed to Shiva. This mantra is to be recited once a day, preferably in the morning, for forty five days.Begin on a Shukla Paksha( Waxing of the Moon) Chaturthi, Panchami,Shasti or Sapthami.

This Mantra Contains Vashatkaara, which is personification of Vishnu.

‘Viswam Vishum Vashat Karo..Vishnu Sahasranama
