Hi Tony,
DO NOT, under any circumstances, install or run either of these programs. They are both scams. A quick check on Google reveals that both are available to download from numerous locations and sites. This is usually a good giveaway that they are not to be trusted. They appear to operate in the same way as numerous other programs of the same ilk - they scan your system and find umpteen errors in your registry and then want you to fork out money in order for these errors to be "fixed". They do nothing of the sort and you end up with malware on your system that can be difficult to eradicate. They have even been known to find registry errors in a CLEAN installation of Vista.
