Have you Googled the IP in question? Quite possibly unrelated, but there are several hits that contain suggested fixes.
If your account has admin privileges, then you don't need to make another account. Just take ownership of the folder with the host file in. host file may be also set as read only, so may need to take that off while you take out the line of text.
To take ownership, right click on the etc folder -> Properties -> Security Tab -> Advanced Button -> Owner Tab -> Edit Button and then click yourself and apply it. This should let you edit the file and remove the line of text that is redirecting google.
