Unusual tracking cookie?

First I know for the most part, tracking coookies are not a MAJOR security issue. But the last few scans (full and quick) have found this rather strange cookie noted asfound. Given recent possible infection of my machine, I thought I would get feedback on this.

Usually when the tracking cookies are found, they log as such:

for example

 

JoeSmith@ atdmt   or JoeSmith @NHL.com   or JoeSmith @Norton   

 

but this is the strange one I found

 

Orphan Cleanup

 

does not note my PC or a place

can anyone shed light on this? Is this a bigger issue of security?
