How do I completely get rid of iYogi software?

Actually those files possibly locked by another programs so you can remove it, if you are wondering about msconfig, you can click windows>accessories>run>and type msconfig on run box. But I don't actually know how to remove it manually with msconfig, usually I use software that can help me to move some files that can not be removed, you can download it here a href="http://longpathtool.com/" rel="nofollow"http://longpathtool.com//a it's working well for me so far.
