Suspicious.Cloud.9 Exonerated

I was scanning my PC a few minutes ago and afterwards I went to check to make sure all the stuff it had detected was cleaned out and happened to see quite a few Suspicious.Cloud.9 Exonerated listed in the security history. I had not gotten any warning of what it was and it says for them that it is a statistical submission and that it's status is still pending. There was no virus detected or anything during the scan and I have no clue what this is. The Nortons website says it's a detection technology while some posts I found said it was a highly infectious trojan that would ruin my PC. What is this and is my PC actually safe?

 

Sorry if this is posted twice but I hit save and nothing showed up.
