It is malware.
Run a few antivirus scanners. I would suggest Malwarebytes first.
Eset does a useful free online scan.
Online Malware Detection | ESET
Has something to do with "cloudfront.net". Amazon shows it as software.
Norton security couldn't find it
Spybot couldn't find it
Removed two references to it from the registry.
Eset found 12+ unwanted references. I failed to identify any with "cloudfront.net". I have a good opinion of Eset.
