Those who are not into the technical side of computers often underestimate the use of firewalls and antivirus programs. There are those who say that antivirus programs are expensive and will just be additional costs. There are those that who don’t turn on their firewall because they just rely the protection on their expensive antivirus program. For those that are not familiar with these tools, they should know that they have different functions but work together to keep your computer safe. One without the other would result to complete system disaster.
First, let’s look at the firewall. Just like the physical firewall, this tool protects the computer from unauthorized access. Pop-up programs and unsolicited malwares usually run when the trigger is pressed or double-clicked. If you have firewall with you, these programs can’t run immediately. Outsiders who will try to get into your system cannot access your system if the firewall is turned on. This is how important the firewall is.
The antivirus program is another important program too. Viruses are rampant and can be troublesome if they begin attacking important files. Just like malwares, viruses can attack once the trigger is turned on. Viruses could destroy files, whether it’s personal or system files. When you have an antivirus program, these will immediately quarantine if not delete viruses as soon as they will be detected. Indeed it is best to install and take advantage of these tools. Without these two important tools, you will have many problems that will be created later on.
