Is the agkn cookie malicious?

when I google this agkn, it seems to pull up a little about a trojan

 

But when I run agkn.com through safeweb, the site shows not a threat

 

it seems this cookie comes up when I go to the home page I have set, which is yahoo.com

 

if I I delete the cookie, then go from there to any other website the cookie seems not to return

 

anyone know if this is malicious?
