Antivirus and Firewall Comparison - Where to Compare Antivirus and Firewalls PDF Print E-mail

Firewalls play an important role in the security of your computer network and are designed to protect your computer, all of your applications and files from the threat of external attacks. Many people overlook the importance of a good firewall and they should definitely consider this type of protection before being exposed to the internet.

One handy tool is an antivirus firewall comparison which describes what type of protection each firewall can provide. There are several different types of firewalls and having the one that suits your needs the best is important.

  1. Packet-filtering: this type of firewall filters "packets" by examining the protocol and address information only. This variety of firewall is simple, fairly low cost and easy to use. Most often these types of firewalls are "built in" to operating systems, such as Windows.
  2. Application level: the firewall is an application proxy overseeing each data exchange remotely. The firewall is "invisible" and monitors all traffic according to specific rules.
  3. Circuit level: the rules are fully configurable, so that traffic is only accepted from an authenticated source, and during a specified time period.

There are, of course, many considerations with respect to the type of antivirus firewall that is best for your particular application. Most antivirus firewall comparison charts set out the pros and cons of each one, helping you to come to an informed decision on whether or not that particular firewall is the one you need to install.

The most important factor in reviewing any antivirus firewall comparison is to come to a decision and to purchase and install this important protection. Virus attacks are on the rise, and network attacks continue to increase and become more sophisticated. Your best defence is a good offense, and that is to have comprehensive firewall protection installed to prevent such attacks.

Antivirus Firewall Software is software that has been created to protect computers and pc's all around the world from hackers, spammers, and virtual infectious bugs that are looking to destroy your computer. Another way to put it, it is used to detect, prevent, and remove computer viruses, worms, and Trojan horses from computers. Understanding the general purpose of antivirus firewall software can really save your computer and motivate your to make the small investment.

There are many strategies utilized by the software to protect the computers. First, signature-based detection involves performing searches for standard malicious patterns in the executable code. Please keep in mind it is possible for a user to be infected by a virus when no signature exists. That goes to show how challenging it has been over the years to protect computers 100 percent of the time.

There are a few drawbacks to using antivirus firewall software. It has the ability to weigh down on the computer's performance while the user is searching the internet or working o a word document, the antivirus software is constantly running which uses some of the random access memory in the computer. The other side is the weight is worth it if it is going to protect your computer.

The only other drawback I can think of is if and/or when the user makes a wrong decision. If the computer user clicks on a program not thinking or knowing it is a potential Trojan horse or malicious virus, it may be too late for the antivirus software to block the virus from entering your computer. The lesson here is to be careful what you click on. Anything that looks suspicious be precautious. Just a short history lesson on antivirus software, there is competing claims that the innovator of the first antivirus product that was also publicly documents was created in 1987 by the man Bernt Fix. Back then, virus were still in use however, they were much less frequent than they are today. In time, as internet usage increased, so did the viruses that would spread from computer to computer.

Some of the more frequent programs including Microsoft Outlook were extremely vulnerable to viruses that were embedded in the body of the email. Unfortunately, in today's society users have the potential of contracting a virus by just opening or previewing an email. Some of the well-known antivirus software out there includes McAfee and Microvirus. I prefer personally Microvirus because it is inexpensive, simple to use, and works just as well as the other antivirus firewall software out there on the market. You do not need a CD to download it. Just the download itself and you are good to go.

We all probably have some experience of contracting a virus on our computers. We all know how painful it is to have to get the virus off our computers and even erase our entire hard drive in order to start from scratch. I deal in computers on a regular basis so I just have a little more experience and history in dealing with viruses. I also know the good software on the market. Ultimately, I hope this has given you an idea of what this software is and how it can protect your computer.
