something missing

  stav6758 10:21 07 Dec 05

Can anybody help me.I bought a acer computer where windows,norton antivirus was already installed on the hard drive.The problem is the norton antivirus subscription is now finished,so I deleted this so I could put on mcafee antivrus because I'm already sighed up and paying for it.
The problem is when I took away norton,this has messed with windows and has obviously deleted some files to make the system run.Some things run like the internet but things like media player don't.I also can't operate the systems restore.
Is there anybody out there that can point me in the right direction please.

Do you have a windows CD?

If so, run the system file checker
