The main objective I have is to find a way to secure the future eternal use of Windows XP on my PC without worrying about being hacked or catching viruses , spyware , trojans and malware and being forced to upgrade my OS which I do not want to do.
The only true way to do this is to disconnect yourself from the Internet. While that is true for all computers, it is especially true for any computer running an outdated operating system.
As time goes on, security exploits will be found for Windows XP and Microsoft will not be patching them. Software vendors have dropped support for Windows XP already and most will be sure to follow.
I highly suggest switching operating systems -- Windows 7 is not very different from Windows XP from a home user's standpoint. Though I would avoid Windows 8 if you do not like change.

As for your original question, I have minimal experience with these programs. In that minimal experience, I have only ever seen it prove to be beneficial in a lab (IT testing environment) and schools.
