ok so i went to delete the Mcafee security center and about 10sec. later my mouse stoped working. i got the mouse to work but now when i click on some things it will open up but nothing will be on the page and sometimes things won't open up at all, i can't even go into system restore or when i play halo online a thing pops up in the corner and it will keep freezing for like 10sec, any idea what this is and how i could fix it'? please help
