Norton 360 scan question

Hey,

Sometimes I will run multiple scans at once to save time in scanning my desktop and laptop. At times I will run a Quick and Full scan at the same time and sometimes I will even run a custom scan and NPE all at once. I wanted to know does this affect the outcome in any way? Can you run multiple scans at once or does each scan need to be one at a time? All scans are Norton 360 scans. 

Thank you!
