Just blasting it isnt a option. It could make the situation worse. A bunch of small asteroids is way worse then one big(same reason they use multiple small warheads on nukes instead of one big).

Just gently pushing it out of collision course is the way. Like carlos said with the sunlight reflecting satellite or another option. You realy dont need much thrust at all. Just a small ammount of thrust over a period of several months.
