Since you now have PGP, might be a good idea for you to get into WOT.

Web of Trust the browser add on?

Thanks for that I'm a newbie when it comes to things like this any other useful software that I should check out?

What OS are you using?

Currently windows but willing to install linux if it's got some useful software which you could recommend.

Yeah, http://gpg4win.org/index.html is the easiest software to use. But I prefer GUI-less linux.
