Disable Security Center

Ok so here follows my problem:

I am currently testing windows Vista. Due to the network I am under I turn
off the following settings: Windows Firewall. Due to the machine being frozen
using Faronics Deep Freeze, I have also shut off the automatic updates. My
Virus scanner settings are also "potentially unsafe" according the security
center." I have changed the settings in the security center to get the
bubbles to stop popping up and telling me my machine is unsafe, but the
taskbar icon is still there. My question is: Is there some way to turn off
both the TaskBar icon and pop-up bubbles for the the Security Center. Better
yet is there I way to turn off the security center all together
