Is VMWare a security boost?

[SweetPea]

I'm afraid I know nothing of the inner workings of VMware. I have a few questions.

Assumptions:
1. I've built a virtual machine that only accesses the internet via the poker clients. No web. No email.
2. The virtual machine has no permissions to see anything on any real computer on my network.

Question:
If the non-vm OS of the physical machine that is hosting my virtual machine picks up a keylogger or trojan, does the virtual machine offer me any additional protection?
