Silver Surfer Play Times

After an attack of Trojan lost Internet Explorer. I can only access it via Firefox. "
Can not access Windows Media Player, and have lost much, but can Play CD's. When I click on IE on the desktop, a small black screen pops up saying C: progra ~ I intern ~ I iexplore.exe can not display in DOS mode. I have windows XP, and AVG and Spybot Search and Destroy which I run several times a week. I'm just a beginner, but also a Silver Surfer, and I'm trying not to lose enthusiasm because of blind ignorance. I really appreciate anyone willing to give me a helping hand.
