Hi Dennis.
No problem and I apologize for violating any forum rule on my first visit.
Why do you consider that site not to be legitimate? Its software provides secure and anonymous communication and is highly regarded. See Wikipedia for more information.
My objective was not to make it appear that you or Piriform endorsed the product. The document enlightened me to the fact that there is residual information in the pre-fetch directory that CCleaner should detect and remove.
Best Regards,
John
