Service pack 2 blocking my .HTML file, what to do?

Hey guys, im making an flash website atm, my problem is that when i publish the .swf and the .html file, when i open my .html file, service pack 2 is blocking the .swf. Its blocking cause of the following reason: 'Opening a ActiveX/Javascript file might be a risk for your computer". Does anyone know how to avoid this??

Hope you guys can help me out a bit.
