Peak Protection 2010 Trojan?

Has anyone heard of the Peak Protection 2010 Trojan?

 

My computer is trying to download a file, http://buy-download.norton.com/downloads/CLT/NAV/US/2011/18.1/ESD/NAV-UPGRADE-ESD-NoDefs-18-1-0-37-EN.exe. I ran "NAV-UPGRADE-ESD-NoDefs-18-1-0-37-EN.exe" in Google, and it said that this was a Peak Protection2010 Trojan.

 

Is this a legitimate Norton product, or is it a virus? How do I remove it?

 

Any help is appreciated.
