Did you know that with a usual system, uninstalling a program will not totally remove all its components including some of the data stored in the registry? This is especially true with antivirus, security tools, PC boost, spyware removers, and the likes. If you want to completely uninstall a security-based application and replace it with another one, try AppRemover.
