The Norton AntiVirus gives alert on not turning on autoprotect, and there is no response when I clicked 'repair' bottom. I suppose it is caused by some sort of virus in my computer. How can I get rid of this? I really appreciate your help.

There are probably too many programs running. Is there any way I can make the computer more efficient? Thank you very much.
