With fireball, do you mean a custom made dummy that slides towards a targeted location, or blizzards fireball that is sent upon a unit dealing damage and stunning him? For the knockback part, I would suggest you to use a knockback system. There are a lot of them around the forum just search for it and you will find one in no time.
Ok I searched and found one for you. Link. If you need further help just post again and ask.

not really what i was looking for
i need one where when it hits the Unit it flyes with the Fireball until the Fireball Disapeares like in the map "The Predator"
So... First of all do you have the trigger that creates the fire ball and makes it slide? If not you can use and modify my rocket launcher spell. Link. And if you want the unit to go with the unit you will need a trigger that moves the unit to the position of the fireball. You could add this to the rocket launcher as well by creating a unit group around the fireball, pick every unit in the unit group, move them to the fore ball's location.
Finally finding about some of the bots that are flooding the users online - bytespider apparently is a huge offender here - ignores robots.txt and comes in from a ton of different IPs
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
