I was looking at logs and this image came up Imgur: The magic of the Internet
What does this mean? Other files came up with the exact same text (exonerated) do I need to be worried?
No worries. 
Thank you, I was worrying over nothing.

Norton Community Watch collects information about potential security risks from your computer and sends the information to NortonLifeLock for analysis. This helps Norton identify new threats and where they originated more efficiently and provide solutions to block them.
Norton Community Watch only collects information on running processes, visited URLs, or general system information from your computer when Norton detects a possible risk. It sends data for analysis during a LiveUpdate session or when a scan is run.

A statistical submission is generally something that is used to refine virus definitions to make them more accurate and less prone to false positives. So if a statistical submission says that a file is Heur.AdvML.C exonerated, it means the file is not Heur.AdvML.C. [credit SendOfJIve]
Norton Community Watch is not a malware detection component. It sends files of interest to Symantec for analysis. A statistical submission is generally something that is used to refine virus definitions to make them more accurate and less prone to false positives. So if a statistical submission says that a file is Heur.AdvML.C exonerated, it means the file is not Heur.AdvML.C. The file will be submitted to Symantec though, and if necessary, the virus definition for that malware may be tweaked to make it more precise and less likely to cause possible false positives with that file in the future. If the file had actually been Heur.AdvML.C, Norton would have removed it.

This is too technical...
I'm guessing "Heur.AdvML.C Exonerated" means you've restored a file from quarantine that Norton had previously detected as Heur.AdvML.C, indicating that you think it was a false positive. Norton then submitted this information to the server, presumably to reduce false positives and improve its Machine Learning algorithm.
