What are the chances that the ones marking as malicious are owned by media conglomerates that are losing money because of the service 12ft supplies?

Website scanning for malware or other undesirable content is extremely unreliable and prone to false positives. None of the three vendors are very well known (except for a few other reports of false positives). If anything that's a pretty low hitrate on virustotal all things considered. Don't put too much stock in the heuristics of companies whose business model revolves around scaring their customers and exploiting computer illiteracy.

3/92 on virus total is a great result. The only scanners reporting a problem are the ones that are always wrong.
