HijackThis! is a good program to use that detects odd or unknown services, and lists what they likely are, and the path/reg key, which is also usually a clue as to the service's/program's/daemon's legitimacy. It detects red-flag BHOs, registry hooks, and especially, hijacked browser homepages! It appears that is what happened to you---your homepage got hijacked...you got browser-jacked! Try running that, and if the ssue(s) is/aren't intuitively obvious or glaring, then there is an option and a site to and to where you are able to submit a copy of the generated logfile for a comprehensive break-down and explanation beyond what HijackThis! natively includes.
