The only security I have is "McAfee" Security.
and there are no error messages, it's just everytime after I turn off my computer and I go back on it later the Lime slice thing that is on my desktop is gone and it is that white rectangle page thing, and it says something about needing to install it again, sorry I don't remember the whole thing that it says.

Sorry that isn't much help, I don't know how to explain it. I feel pretty stupid, and useless to try and help my own problem.
