This is precisely what I mentioned in a previous thread here (http://forums.cox.com/forum_home/internet_forum/f/5/t/19458.aspx?pi287=2), that "the reality is also that Cox as well as their competitors are all experiencing increased complaints of greatly increased data usage, far beyond what had typically been routine daily consumption. The reasons for this are many and varied. Some are the result of forgetfulness or a lack of vigilance on the part of the customer, while in many cases there may also exist a definite source or cause of intrusion, penetration or "leak" in their network, the solutions of which may also be far beyond the remedies that Cox supplies."
Tell me again, Cox, how Gerald Howell's anomaly can be mitigated by your Data Usage Meter, Data Usage Meter Calculator or by visiting the recommended https://www.cox.com/residential/education-center/internet/data-usage.html?
