Do the surgical masks that I see everyone wearing protect against viruses?

So, I've seen and hear of people wearing surgical masks or some variant of them when traveling, in order to guard against various strains of the flu.
Can these masks really protect against airborne viruses? My understanding is viruses are much smaller than bacteria or fungal spores. Do surgical masks adequately filter out viruses?
