I have a problem with my computer. The process Iexplore.exe is opened in the background and using most of my PCs CPU. Sometimes I hear random music playing from my speakers. This music stops when I close the process Iexplore.exe. Once I close this process it is usually there again within five minutes or so.
I have already run many anti-virus programs including AdwareCleaner and Hitman Pro, but the problem is still there.

I hope you can help me. If you need more information conscerning my problem, please contact me.
