What setting do I put my digital camera on so that I can take a picture in the mirror without the glare? - indoor shot put

I have a Canon PowerShot SD 1000 and need to know what setting I do not understand them to put the light. Normally there is an internal configuration, because I most of my shots in my house on. When I try a mirror and a shot that was destroyed by a fire approach. What can I do to avoid, and have a clear idea?
