You're welcome

Registry cleaners are also mostly unnecessary, there's really no need to use them. I found out this the hard way, after I used RegistryMechanic or something from PC Tools with a registry cleaner (it claimed to speed up performance... yeahhh right) and then a bunch of "windows installer" boxes came up, staying I needed to reinstall several programs, so I ended up uninstalling them (since I didn't have the installation CD's), and it kept happening with more programs every restart. I was so fed up! I ended up downloading the Windows Installer Clean-Up tool, and that seemed to have taken care of the problem.
As for what a rogue is, a rogue is generally described as a program that does one or more of the following (if anyone has anything else to add or correct me on, please feel free to jump in here)!:
* Produce false positives/lots of entries that don't need attention in order to get the user to think that there is something wrong with their system
* Prompt the user to purchase the software before removing any detections (note: not all programs that do this are rogues, but when a program asks you to purchase it before removing anything, generally that's a red flag. For example, Spyware Doctor from PC Tools is legitimate, but it asks you to buy it before removing any detections, which isn't a good thing, why put sensitive personal information into a potentially compromised system)?
* Program pops up on the screen after surfing the web, or randomly, without any user interaction (user didn't install the program, didn't know it was on his or her computer... etc)
* Lots of annoying pop ups telling user to purchase program or remain infected, telling user that their system isn't clean, etc...
As for the company behind RegTool, I am not sure. Maybe one of our staff members or experts will know the answer to that
