This security measure provides the first line of shield only.  Thus, pc users may need to install other software that protects against other harmful agents like e-mail viruses.  Upon installing a firewall, an anti-virus software must also be installed, because aside from protection from unwanted internet traffic, computer virus protection is another badly vital part to be well thought-out. 

Protecting your computer is of vital importance because without this measure you leave your computer, its files, and data vulnerable.  In business establishments, the computer protection is of primary interest because prized information is exposed.  One harmful software or computer virus that manages to control the system could wipe out all the day’s information and set off work interruption.  In large business establishments, this could lead to a great deal of financial loss.
