Protego!
Protego is the shield charm, a spell that creates an energy barrier which deflects minor to moderate hexes as well as physical objects. It will not repell any Unforgivable Curse. The Shield Charm is a moderately difficult spell. Fred and George Weasley realized that most adult wizards, even those employed by the Ministry of Magic, could not produce a functional Shield Charm. They used this to their advantage when marketing their line of protective clothing (hats, cloaks, etc), upon which Shield Charms were cast.
