Activity Monitor issues after Lion install question.

I installed Lion yesterday and noticed everything is running slower, although, I have Applecare for 90days they think everything OK. <<Not.. Anyway, Activity Monitor has; Flash Player (dashboard client internet plug-in)@..%CPU 70%. PID 770. I'm just asking, "should i end/quit process" and keep doing it or any idea what i can do. By the way, I see this is not a new issue, just cant find the answer for mine. I hope i can put this post on here and be alright with it. I just don't have no thread knowledge experience yet. Thanks A LOT.
