Neither - the influenza VIRUS is not typed by gram stains - only bacteria are.

Gram-positive bacteria and Gram-negative bacteria are different in their colouration when dyed and viewed with a light microscope. Gram-positive appear violet, and Gram-negative appear red. Gram-positive and Gram-negative classification, however, has nothing to do with size.
Nostoc is a type of cyanobacteria that contains both gram-positive and gram-negative characteristics. It does not fit neatly into the gram-positive or gram-negative classification system due to its unique cell wall structure.
