Temporarily Completely turn off norton internet security 2010

I have two questions i would really appreciate some help with: 

 

1. How do i completely disable norton temporarily. In the tray i am able to right click and disable firewall and auto protect but a lengthy backup failed becasue norton decided to do a full system scanning while it was running. I want to know how to temporaily but COMPLETELY disable internet security 2010 all features.
2. my backup software manual suggests i "disable 3rd party anti-virus and backup software from scanning the following folder and subfolder:

•<..\Program Files\GFI\GFI Backup 2009 - Home Edition> ".

Please explain how i direct norton to do this.
