    Default Difference between anti virus and firewall?

    Hey

    An antivirus checks files to see if they are infected (don't ask me how). A firewall checks network activities and allows some but not others. An analogy would be a house, and diseased people living in or outside the house. An antivirus checks the people inside the house and tells you if they're infected. A firewall stands at the door and only allows approved people in or out of the house.
