Why would Symantec Antivirus stop you from installing and playing games? It's an Antivirus, it's purpose is to make sure no viruses are on the computer.

I see, what does Symantec Antivirus have to do with that?

Wouldn't it be just user restrictions?

Somehow get Administrator. Maybe boot in to OPHCrack with some rainbow tables ;)

What os are you running?

Just bruteforce/reset/create a new local admin account...

I am able to access the C:/ drive but only documents I have saved on it, all of the important files are in restricted areas I am not able to get into.

My school had the same set up, you couldn't access the C:/ drive where program files were kept.
A few of us got round this by; right clicking on a program shortcut in the quick start menu (like Photoshop) and clicking find target, or 'open file location' for vista, this took us to the C:/ drive where the program files were kept, pretty basic but our school overlooked it :)
