help with about:search hijack!

I'm at my dad's house and he has a problem with about:search as his home page and my brother already fixed it for him once, but it is back. I thought about trying to fix it myself, but thought I would ask for help from the experts first since I'm certainly not that! Please help!!

Here is his log...

I can see the problem areas, but when trying to remove the program "my search bar" from his computer it said that he could not because of an error with an mwsbar.dll and I don't see that above in the log. Any suggestions on that??
Thanks
