looking for a program that will erase every bit of junk data/folders/traces and whatever else left behind from programs i uninstalled and other miscelanious crap, my computer has become very cluttered with crap

 

CCleaner.

CCleaner - Download

I use it after every single session to clear stuff.

 

but it doesnt get rid of junk data and folders left behind from uninstalled programs, i need a complete tuneup

 

I don't know what's the problem on your computer, but it clears all the junk I have even after uninstallations.

 

Download CCLeaner and Revo Uninstaller from here: Ninite - Install or Update Multiple Apps at Once

When you are uninstalling a program in future, use Revo and it should get rid of all the junk files left behind
