HijackThis?

Download HijackThis:
http://www.spywareinfo.com/~merijn/files/HijackThis.exe
Save it in a convenient permanent folder such as C:\HJT\, double click HijackThis.exe, and hit "Do a system scan and save a logfile".

When the Notepad window opens, do Ctrl-A to Select All, and copy its contents here. Most of what it lists will be harmless or even essential, don't fix anything yet.
