What is "Yahoo! Detect"?

My ISP - ComCast - sent me the new Norton 360 a couple of days ago. The new System Insight app tells me that an application identified as “Yahoo! Detect” (or possibly “Yahoo! Detector”?) was installed on my machine. I cannot find any information on “Yahoo! Detect” on-line. Not surprisingly, Yahoo help does not reply. I cannot locate any files related to “yahoo! Detect” on my machine. Any advice or insights? Thanks!
