For any computer user it is essential that you maintain up to date, and effective antivirus firewall software to prevent malicious software from infecting your computer. These rogue and damaging programs can be installed without the knowledge of the computer user through email, instant messenger programs and even photos that are sent to you, and can corrupt or delete important documents and files from your computer. Ultimately they may destroy the operating system, making your computer unable to work.

Antivirus software works by detecting viruses that have been downloaded onto your machine and deleting or healing them by moving them to a vault where they are isolated and unable to do further damage. It also attempts to detect threats before they have been downloaded, and then blocks their installation.

Firewalls work differently, by blocking access to your computer for some internet traffic. An antivirus firewall program combines the benefits of both of these to give the highest possible level of protection to your computer. It should be the best chance for any computer user to remain clear of viruses and other malware.

By running a reliable antivirus firewall you are not only protecting your computer from viruses that reach it as well as removing those that manage to install themselves. But you are also providing a barrier to certain traffic, as the firewall will ensure that traffic from certain known dangerous locations is blocked from accessing your computer altogether. This ensures a double edged approach, both blocking the majority of known threats and then being able to heal anything that slips through the net.

When the time comes for you to buy antivirus firewall software you will need to find a program that will suit you. Specifically it will have to work with the computer operating system that you have on the machine, and will have to work within the free hard drive space, memory and processor power that you have. It should also meet your needs as far as automatic updating and regular scanning of your machine are concerned.

You don't have to pay above the odds by going to a computer store, when instead you can get affordable computer protection from an antivirus firewall shop such as http://www.antivirus-firewall.info/ Here you can review your available options and find the best antivirus firewall program for your needs. You can also see other possible options for your protection, including standalone firewalls that will work alongside whatever antivirus program you are currently running.

Though some antivirus firewall software suites come on a CD or DVD ROM, many are available for instant download online. This is to ensure that you are able to protect your computer right away, rather than having to wait for a disc to be mailed to you.

It is important to remember that you don't have to buy a program that is extremely expensive to gain effective and reliable antivirus firewall protection.
