Microsoft Windows deploys FIREWALL to prevent these assaults from occurring. Firewalls stop hackers or unwanted elements, such as worms or virus, from entering into your computer. Since your computer is attached to the network or internet, it is very vulnerable from malicious attacks if you are not defending it. With the help of the firewall, any attacks from any computer can be prevented. On the other hand, if your computer becomes infected because of external drives and was not prevented by your anti-virus, your firewall may help you spread that particular virus, for example, from spreading into the internet. In short, you are protected and you protect.
