I am getting the RightMedia tracking cookie on my computer repeatedly.
Avast! does not appear to be picking this spy-ware up.
What can I do about this?
Thank you.

Download Malwarebytes Antimalware (MBAM) and install it.
Before running a scan, update MBAM so that you have the most up-to-date detections.
Run a quick scan. Post the results as an attachment.
You can get Malwarebytes Free directly from the majorgeeks website here: http://www.majorgeeks.com/Malwarebytes_Anti-Malware_d5756.html This is safe to download, unlike using a site like c|net downloads. c|net has been problematic for some users over there.
Be sure to update to the latest definitions before scanning!
avast and malwarebytes does not scan for tracking cookies as they are not malware. 
if you want to spend time on cookie scan… superantispyware will do it fore you
or just empty you cookie folder with CCleaner
Are cookies really spyware and are they dangerous?

What is actually detecting this ?
You could start with your browser settings (you don’t say what that is ?), don’t allow 3rd party cookies, e.g. those that don’t belong to to the site you are visiting. That gets rid of the greatest majority of so called tracking cookies.
Depending on your browser you can use something like the firefox CookieMonster add-on to manage cookies.
This is the Malwarebytes report
It does not pick up the Right Media tracking cookie but it seems that this cookie slows down my computer.
Spybot picks up this cookie but it keeps on coming back.

Use ccleaner to clear tracking cookies: http://www.piriform.com/ccleaner/download/standard
tracking cookies are not viruses…what MBAM shows right now in your log…is just orphan registry keys…not malware or viruses. :

About the MBAM detect → PUP means Potentially Unwanted Program. Although these aren’t malware as such, I wouldn’t advise having them on your computer as PUP software comes usually related to spyware and adware -and browser helper objects as toolbars, extensions etc.
