How Can I Totally Uninstall BitZipper As I’m Unable to Get Rid of It in Windows 7 Laptop

I’m trying to uninstall BitZipper but when I do, I am told I have insufficient access and I must contact a system administrator even though I am one. I've also ran "default programs" as an administrator. Unfortunately, I’m failed. It is not valid. I think you might have tried many ways to get rid of BitZipper completely since you searched its removal guides from Google on the internet. 

However, most of them are not helpful or complicated for you. Fortunately, I have found an useful BitZipper removal tip to solve the problem successfully. You could avoid that trouble if you could carefully follow the software uninstall guides step by step in this post.
