Shielding Your Computer with Antivirus Firewall Software

Shielding Your Computer with Antivirus Firewall Software

The only time that you can safely say that your computer is safe from attacks, malware, and viruses is when your computer is either off or disconnected from the network. But, since such a computer is practically useless for the tasks of the modern-day workplace, connecting to a local network or to the Internet has become a necessity. Is there a way for your online life to remain safe and healthy? One important way is to use antivirus firewall software.

Antivirus firewall software often comes as a bundle of separate programs packaged into one security suite. Though, there are antivirus programs that can be installed as stand-alone applications. There are also stand-alone firewall programs that can replace the bundled basic Windows Firewall that gets installed with recent or updated versions of the Microsoft Windows operating system.

Antivirus software and firewall software are both protective measures for your computer. They have different ways of protecting your computer. For this reason, it is important that you install both (if buying separate programs for each), or make the job easier by choosing an antivirus firewall software suite.

How does an antivirus program protect your computer? To answer this question adequately, you have to understand how computer viruses work. Computer viruses are software programs or computer codes that display two specific characteristics. The first characteristic of a computer virus is its ability and intent to destroy data on your computer. The second characteristic is its ability to reproduce copies of itself and to infect other computers. If your computer is connected to a network, it is easy for your computer to become infected by other virus-infested computers on the network or to infect other computers if your computer is infected.

An antivirus program helps prevent the spreading of computer viruses. The antivirus program relies on technology that allows it to detect virus infection in software programs. Most antivirus programs also allow you to choose how to deal with an infected program or file. In most cases, you can instruct the antivirus program to try to remove the malicious code that has been injected into a program, or to completely delete the infected file or program, or to isolate the program. If you have antivirus firewall software installed on your computer, it should be able to perform the job of an antivirus program and a firewall.

How does a firewall program protect your computer? A firewall program works very much like a real firewall--a wall that prevents fire from spreading from one building to the adjacent ones. A firewall program does this by "listening" to computer ports where data and information pass through. If the firewall program detects unusual or unexpected activity in a port, it will alert you so that you can deal with it. Or, it will automatically resolve the issue based on instructions that you save in a configuration file. A firewall program can block connections from the outside world that may open up your computer to virus infections, malicious attacks, unauthorized of software that can harm your computer, and other threats. To get the most protection for your computer, it is advisable to install an antivirus program along with your firewall program, or to install an antivirus firewall software suite.

By installing antivirus firewall software, you avoid making your computer a sitting duck for various destructive and malicious attacks from the outside world. It should be the very first thing to do after installing your operating system so that you won't have to lose very important files and data on your computer.
