I'll check on that, but I am concerned since I cannot set my search page back to it's original default nor can I reset my home page to its original. Apparently, Microsoft has them "hijacked" to always set to a microsoft area.

Any ideas why? I am usind spyware blaster and spyware guard, and when SG tells me that my search page default is changing to MSN search, I tell it to discard the change. However, doing so causes the SG alert to come up again and again until I accept the new value!
