It seems a software to crack Microsoft products is present on your machine.
If you shouldn't be aware/conscious of it, I suggest you a full scan with your antivirus and antimalware.
By the way, it is better (faster and more secure) to use an antivirus offline (example: kaspersky rescue cd, that's free).
If instead you should be aware/conscious of it, you should also be aware that
in public (and serious) forums it isn't allowed to help (nor trying to help ) someone who activated software with cracks (or similar tools, however they are called).
You have to purchase and install a genuine copy of that MS product, or you should uninstall that MS product and its related crack software.
