Anti-jinx

"Oh, its a simple enough anti-jinx, but it's not so much having to repair the damage, it's more the attitude behind the vandalism, Harry. Muggle-baiting might strike some wizards as funny, but it's an expression of something much deeper and nastier, and I for one-"

- Arthur Weasley

An anti-jinx is a type of spell that prevents the effects of a jinx over one target, object or animal.
