Like I do not want to have to buy something for it when I know there is a way to do it without spending money so please may someone show me how and steps of what i have to do ?
How to de-frag your hardrive

I installed both of those firewalls and removed them. Yet Vista keeps reporting that they are running. I am having problems with them now. I even ran a registry cleaner, still Vista keeps reporting that "multiple firewalls report that they are turned on."

How do I fix this problem, I want to completely remove them?

Thanks for helping me
