Below is a rare recording of St. Porphyrios of Kavsokalyva (Dec. 2) praying over a few people that they may be protected from all evil and harm. The prayer is transcribed below for common use.
O Lord, save Your people.
Our God, Father of our Lord Jesus Christ, grant (name/names) health and strength of soul and body, and protect (him/her/them) and banish from (him/her/them) all spells, magic and maleficence. Protect (him/her/them), O Lord, and preserve (him/her/them) from all evil, through the intercessions of Your most pure and holy Mother, and of all Your Saints. Amen.
And grant (him/her/them) prosperity. Amen.
Lord Jesus Christ, have mercy on us.
