All of this is essentially correct from my experience. If your computer is running in guest mode, or even normal user mode, the amount of damage a worm, or virus can do to your computer is virtually nill unless you count loss/corruption of profile data. That's essentially all the virus will have access to change. If it doesn't have permissions to do damage on the target system, it can't do that damage.
