Ok, well first Tracy, welcome and don't panic. We'll get to the bottom of it in a bit..
For now do this in regular mode:
Download 'Hijack This to its own folder
http://www.spyware911.net/downloads/HijackThis.exe
Doubleclick HijackThis.exe, and hit "Scan".
When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, save the log, load it in Notepad, and copy its contents here.
Most of what it lists
will be harmless or even essential, don't fix anything yet.
