Assembly-CSharp.dll.mdb throwing errors..

I keep receiving this error. I believe it occurs because I am on Windows 8.

  Internal compiler error. See the console log for more information. output was:
    Unhandled Exception: System.UnauthorizedAccessException: Access to the path "C:\Users\Account\Documents\Project\Temp\Assembly-CSharp.dll.mdb" is denied.

Basically. I believe it is trying to write or read from it, but due to windows 8 restrictions it’s throwing errors. When it occurs I cannot build my project or even play it in the editor and have to close Unity down completely. Any solutions?

I think it may be your antivirus. I heard something about that interrupting. I am having the exact problem currently. Will look for a better solution.
