Several Questions about NIS 2009 Features

I am considering whether to upgrade to 2009 and also whether to switch to another security software after my current subscription runs out, which is soon.  I felt like 2008 was a major step backwards from 2007, but I had already paid for it, so decided to wait until my subcription experied to make a decision about changing.

 

So my questions are:

 

1.  Does NIS 2009 bring back the "block all traffic" feature that 2008 omitted?

 

2.  Can I turn off the new "continous updates" feature so that I manually initiate all updates?

 

3.  Can you disable this new whitelisting feature that has some programs/files automatically trusted and are not scanned?
