I realize this is a complete newb question. I'm a complete newb.

I've gotten a free Joomla! Jumpbox up and running to host my new website (using VMWare PLayer), and have it on a spare computer over my broadband connection. All seems well.

My question is this: is it possible (either with these free solutions or with an inexpensive paid solution) to add applications (security, AV, etc.) to this? If so, what's the proper way to do that - do I somehow add apps to the Jumpbox, or am I installing additional apps in the VM?

Please keep the answers simple - I'm just wrapping my head around the whole VM concept. Just assume I'm stupid for a while. :)
