I can't understand your first question.
"Will the programs listed above clean my computer or are they just of registry clear?"
That looks like two questions.
1. "clean my computer".
---> MAYBE!!! There are far too many pests and viruses to expect any tools to clean them all.
2. "registry clear"
Not one of the items I've listed so far report or scan the registry for "errors." That's something you find in those other apps. Yes, these will scan the registry for trojan and other pests but your posts make me thing you've fallen for some registry cleaner scam.
As to uninstalling I use the control panel in Windows and if need be the old Delete button on my keyboard.
