I've already done the first 2 and no changes

ok, so a few days ago I was away from msn and when i got back i had a message from a friend on msn..it was a link that said somthing along the lines of "hey is this really you" and listed my email address..I clicked on the link stupidly and when i did that I got a window that said "run or save" i didn't click on either of those, I actually restarted my laptop, but since i did that, every time i log on I get that run/save message popping up. I am unable to fully use msn on my computer. I cannot receive webcams and my msn is freezing frequently. Could someone tell me the simplest way to fix this issue..Please!
