PC Security Step 5 - Should You Have a Firewall?
Wednesday, January 30th, 2008As we have already discussed, the Internet is littered with evil intentions and malicious - albeit smart and brilliant - plotters. They are constantly in the prowl for innocent, unprotected computers. Internet hackers use all sorts of codes such as viruses, worms, and Trojans, to crack into and ruin your computer. You must therefore be prepared to block them off from ever entering your computer’s system at all times.
It is often said that the best cure is prevention. And the saying applies to your computers. If you want to protect your computer from the threat of viruses, worms, Trojans, and other malicious code, one of the best options to take is setting up a firewall.
