Computers are very susceptible to any kinds of
digital attacks. Without security, your computer will definitely be hacked. Hackers are good in doing evil things on the web. They can snatch information on your computer without you knowing it. They are intelligent enough to rob private information from your computer virtually. They are the pirates of the web.
That is why; firewall was created. Firewall protects the computer and files from the attacks of virus, SPAMS, Spyware and other malicious information that are entering the port. If the firewall does not recognize the information, the message will be blocked. Network administrator sets the rules in the firewall. So, if the message seems to appear like a virus, it will be definitely thrown away.
There are firewall software available in the market. If you want freeware firewall, you can get it from Internet. Just choose the reliable and safe website for your
freeware firewall download for security. Some websites provide
freeware software with a virus attached on it. This is the risk of downloading a free software, so you must be careful in picking when choosing a website for downloads.
