Antivirus Scanning

The foundation of any AV software is, of course, the antivirus engine itself. There are a couple of areas where things vary tremendously when it comes to antivirus protection.

Here’s our take on some of the most important things to consider:

antivirus detection accuracy
Each antivirus vendor uses their own mechanisms to detect viruses. Some are highly accurate, detecting the vast majority of threats to your PC; some are terrible, leaving your PC vulnerable to all but the most basic viruses.
antivirus heuristics
Since new viruses and other threats are come out daily, antivirus software needs to detect viruses that haven’t yet been identified. This is another place where things vary significantly from one antivirus manufacturer to another.
scanning speed
Whether you’re manually scanning your files or allowing the AV software to perform an automatic scan, you don’t want to wait all day for the scan to finish. In our testing we found the best antivirus software can perform the task, quite literally, twice as quickly as lesser-quality programs.
resource utilization
As with scanning speed, how resource-hungry your antivirus software is makes a big difference in how your PC performs when your PC is protected.
Low-quality antivirus programs can be such a drag that some users are forced to disable their AV software altogether just to get their PC to have enough free memory and/or CPU to be able to perform a certain task on their computer.
Since this is never a good idea, having software that can do its job while you do your job is critical.

Bidirectional Firewall

Today’s best antivirus software and Internet security software has a built-in (or optional) software firewall.
A good firewall should have the ability to monitor Internet traffic in both directions: incoming and outgoing.
If there’s some unexplained traffic activity you should receive a warning, and the software will block it if it’s from a suspect source, giving you the chance to see what’s going on and allow the connection or block it.
This is particularly important if you have a high speed Internet connection that’s always on because even if you don’t think you’re online, chances are you are, so you’re still be vulnerable to an attack.
This gives you a choice of scanning your PC as you see fit. With the scheduled option you can set the antivirus scan to run at a time and frequency of your choosing.
You can select daily, weekly or monthly scans and the time of day to run it. If your antivirus software uses a lot of system resources you may prefer to schedule it to run late at night or in the early a.m. hours so as not to slow down any tasks you are working on.
On demand scanning allows you to run it at anytime you desire, just click the appropriate button on the user interface.

The Reasons Why Your Computer Needs Antivirus Firewall Software

The real truth is that there are many different ways in which a virus can get into your computer. Some are pretty innocuous, while others will shut your computer down for good in seconds.

If you are the proud owner of any type of computer, then you need the best antivirus firewall protection available. Viruses and malicious software can cause much damage and death to your computer.

The severe ones can change or erase important files that will harm your software as well as hardware. Or, they may target files that are vital to the integrity of your operating system. The less harmful code will stay resident in your computer feeding the infecting site with user information, or worse, personal information.

Additionally, these harmful scripts will slow your computer down greatly while your computer executes this extra, unnecessary load. Without the best antivirus firewall software, you will, not can, suddenly find yourself with an unexpected system crash or failure.

If you are lucky enough to only have the less harmful viruses and scripts, then you may not need to replace your computer. However, you will need to restore your computer to the prior condition before the viral infection. Believe me, needing to recover your computer from such an event is both tedious, time consuming and sometimes costly. If you do not have your information backed up, you will lose a lot of important files. In the worst case scenario, you could end up having to spend even more money for someone to fix it for you. This could mean several days or weeks without your computer, while they are working on the problem.

Having to repair or replace a computer from viruses and other malicious scripts is a truly avoidable problem. Having the best antivirus firewall software will eliminate 99% of infections. Such problem is truly avoidable.

So as you can see, antivirus software is vitally important to the health and integrity of your operating system. It is well worth investing in, because it will save you both money and hassles. You do not have to buy an expensive one to have adequate protection. You do, however, need to make sure that the one you use is reliable and updated regularly.

Constant and automatic updating is very important. It is like a cat and mouse game. Bad people make a virus and then the antivirus software companies recognize and stop it. Then, the bad people make another virus. Again, the antivirus software companies make an update for it. This process occurs almost hourly every day. That is why you need the freshest updates available to adequately protect your computer.

Firewall software is still important, but works this software little differently than virus software. Firewall software protects your computer from rogue attacks on the Internet or a network. It is not always easy to tell from a URL that you are visiting, whether or not any given website is safe. It is even possible for people to fake valid security certificates.

Some people will try to use your Internet connection to gain access to the information on your computer. If they can get in, they may search for personal information that you have stored in it. This could include details that will allow them to steal your identity. Everyone is well aware of the problems that arise from identity theft. It can take years to clear up all the problems it can cause you.

If you do online banking or store financial information in your computer, this is another prime concern. There are many bad programs that have been created only to mine or dig through your computer for banking or credit card account numbers. If they manage to gather these, they can drain your accounts or run up your debt in just minutes.

A good firewall is always actively running on your computer. It monitors for just such intrusions and can deny them access to your sensitive information. In most cases, you will see a warning pop-up that lets you know something or someone was trying to gain access. This is just another example of a case where prevention truly is the best remedy.

Recently, there have even been a few good free programs made available that you can use. They are available for personal use and can be of great help. Sometimes, there are occasions where people just cannot afford to pay for these programs. They are not, however, usually a great choice for people that always constantly surf questionable websites. Remember, this antivirus firewall software is free.

But, if you find yourself making only limited use of your computer, they are perfectly adequate. Most of them will update automatically and provide real-time virus and firewall protection. It really just depends on how much protection you need. If you are not certain, then you should do some research and consult someone who is knowledgeable.

I cannot stress enough how important it is to have antivirus firewall software installed. Your computer is an investment and the less time and money you have to waste on it, the better. While you may never need these programs, if you do, you will find yourself very glad you had them running.

Do I Need Antivirus Software?

Absolutely!

Antivirus Firewall software is a must. It may be the most important software you’ll ever install on your Microsoft Windows computer.

As a computer user you’ve probably come across terms like viruses, spam, Trojan horses, worms, etc. Some of you may know what these refer to; others of you may have heard of them but have no idea what they mean. In a word they mean: DANGER!

We can’t emphasis this too strongly. Anytime you go online to shop or to access your email or just to surf the web you and your pc are vulnerable to attack by dangerous elements.

These threats come in many forms and sometimes they can come from sites you’ve been to many times and “trust.”

The virus and malware writers are now taking it upon themselves to take over reputable sites and install viruses, worms, trojans, and the like on these otherwise reputable sites most often completely without the site’s owners ever knowing it has happened.

In essence, these and other malware attacks are attempts by disreputable individuals to disrupt the proper operation of your computer; in some cases rendering it useless. Others can cause you financial ruin.

Think, for instance, that if all the important information contained on your pc was suddenly wiped out. All those priceless family pictures-gone forever. How about the novel you’ve been writing and didn’t make a copy of? Whatever you hold nearest and dearest has disappeared and you can’t begin to replace it.

Then there is the danger of identity theft. If someone can get your social security number, banking, or other financial information it can mean months, if not years, of suffering.

Antivirus Software: What To Look For

A good antivirus program should keep your system virus-free without bogging it down. They are available as standalone programs or as part of a comprehensive security suite. Here’s what the experts say to look for when choosing antivirus software:

* A good detection rate is key. Several third-party companies test antivirus software for detection rates. Mary Landesman, About.com’s guide to antivirus software, says, “Before considering any antivirus solution, you should check their ItW [In the Wild] certification by consulting any of the following: VB100%, ICSALabs or Checkmark.” Most mainstream products perform well, including those discussed in this report. (Note: ConsumerSearch is owned by About.com, but the two don’t share an editorial affiliation.)

* Check the system requirements before you buy. If you are using Windows XP, Vista or Windows 7, any current antivirus software will work. If you have an older or slower computer, however, a large antivirus software program can consume a huge percentage of your computing power. Check our Comparison Chart for system requirements for the software included in ConsumerSearch Best Reviewed.

* An intuitive interface makes software easy to use. Because antivirus software can be customized in many ways, it’s important that the interface guides users through the various settings.

* The ability to update daily is crucial. Most software provides one year of unlimited free updates. After that, you must renew your virus-update subscription, buy a new version of the same program or switch brands. Virus signatures are specific strings of binary code that can be detected by antivirus software. Most programs will automatically check for updates. Some free software relies on a manual check.

Free Anti Virus (anti virus gratuis)

To assure that you always get the best possible virus protection and avoid downloading software that could be adware or spyware in disguise, our recommendation is to stay away from freeware as a general rule. There are a lot of legitimate antivirus and computer security developers out there, though – and they offer very reliable products.

Free anti virus software is available in many forms. Most major internet security product developers offer a free “trial version” to test before you buy. This type of free anti virus program is either time limited (it quits working after a certain period if you don’t buy) or has limited features. A free antivirus download of trial software is a good idea in order to see if you like the product. As long as you download the product from the official vendor website, you need not worry about infecting your computer with malicious spyware. Several good antivirus products to try are McAfee anti virus, Norton antivirus, Avast, Nod32, EZ anti virus, AVG and Panda. See our antivirus software page for information and links.

For those on a tight budget, there are some good free anti virus downloads out there. To avoid downloading from an unscrupulous site however, please either use the links on this page or go to a good software review site like PC World or PC Magazine.

What is a Computer Virus?

A virus is a computer code that has been designed to “spread” and replicate itself by passing from computer to computer. It is a piece of software that piggybacks on legitimate programs like Excel, Word, WordPerfect, Outlook, etc… When the program is run, the virus is triggered to run too. Viruses can be destructive in nature, and can cause a wide range of problems ranging from operating system and file corruption to getting blamed for email spamming. Some viruses are just annoying, but cause no damage.

Viruses usually find their way into computers through networks (local networks as well as the internet) by taking advantage of unpatched security vulnerabilities (holes) in software or by receiving an infected file via email, download or shared disk. Depending on the type of virus, it may be embedded in an Excel or Word file, or may be designed to infect upon the opening of an email. Once infected, a computer can literally infect thousands of other computers by quietly spreading the virus without the user even knowing about it.

Anti Virus Solution

Computer viruses are highly prevalent in our world today, and unless your computer is running as a stand-alone machine with no connection to the internet and you never transfer files to it from floppy, USB or CDRom, it is essential to use some form of anti virus software. Anti virus software is designed to identify and destroy (or isolate) all viruses as they are introduced to your computer. Because new viruses are introduced every day, even the best anti virus software might not work if it is not updated regularly. For an anti virus solution to work properly, its database must be updated regularly with the newest virus definition files.

How an AntiVirus Product Works

An anti virus program watches for viruses, catches them before they execute, and kills them. It works by comparing certain data activity and known virus file patterns against it’s database of known virus definitions. When it finds a virus, it kills or disables it based on instruction supplied in it’s database. Because anti virus software is only as good as it’s last database update, antivirus definitions must be downloaded and installed on a regular basis (preferably daily).

Choosing an Anti Virus Program

There are many good antivirus applications on the market today, and many of them are free. All basically work the same way, but some are more accurate at detecting and removing viruses (assuming the virus definitions are kept updated). Some anti virus products are easier to install, configure and update than others. Some have a lot of advanced configuration options, and some have a pretty simple interface. Some have great technical support, and others do not.

Because computer security is so important these days, our recommended anti virus program is one that comes from either a large computer security company (like Symantec or McAfee – just two examples – there are more), or a highly specialized developer of internet security products (like Grisoft AVG Anti virus, BitDefender, AVG Anti Virus or Bit Defender). Below you will find a summary of great antivirus products to consider as well as links. As long as you stick with tried-and-true anti virus software that has a good track record for accurate virus detection as well as tech support, you’ll be in good hands.
— Remember to update those antivirus definitions often, though J —-
antivirus software included in internet security suites

Many other fine anti virus solutions are available as part of a computer security suite – or internet security suite. Antivirus is packaged with other useful pc security software such as a personal firewall and anti spyware, anti adware software. Information on well known and recommended internet security suites like Panda Software Platinum 2006 Internet Security, eTrust Internet Security Suite 2006, Nod32, F-Secure Internet Security 2006, PC-Cillin, Norton Internet Security and more.

Antivirus vs. Firewall Protection

A Firewall monitors open connections and like an antivirus can monitor email retrieved with mail clients like outlook, for worms and such, but it does NOT act in place of a virus scanner. It just looks for unusual file attachements and the like.
Firewalls also block unwanted inbound and outbound traffic or connections via IE or any other program that connects to the internet for whatever reason, and you can allow or deny any program access to the internet.
You can also configure a firewall to block cookies, ads, popups and websites that you specify.

An antivirus analyzes any file that comes through your system for all known viruses in its virus definition database, and cleans, quarantines, or deletes them per your choices of settings.

Antivirus would have no compatibility issues with setting up internet access via a home LAN, but a firewall would have to be configured some, to allow the computers to access each other and the internet.

If there are any performance issues, they would be negligable, but a tiny loss in performance is a small sacrifice to make, as opposed to the alternative.

I myself, use both, and would recommend the same to anyone.

Choosing the Best Antivirus Firewall Software

Nowadays, more and more people are using computers to get their work done. The popularity and functionality of this machine is so phenomenal it’s no surprise that many threats, like computer viruses, are steadily rising, altering, and destroying computer systems. Worse, it could also ruin the lives of unsuspecting people to some extent. What used to be a luxury a few years back, buying and installing an antivirus firewall software has now become rudimentary for anyone who wants to make sure that their computers-and lives-are safe from malicious hackers.

If you’re one of the millions who surf the Web on a regular basis, you should really consider installing an antivirus firewall software that will protect your computer and provide you online security. However, many are at a loss when it comes to choosing what software to buy. To help you make better decisions, read on for some helpful guidelines when buying this type of software.

First thing to do is to ask friends and colleagues for referrals. Inquire about their personal reviews and ratings with the brand of software they’re using before you buy one. Their responses are guaranteed honest and unbiased and you will have a first-hand account of how different antivirus firewall software work. You can use their opinions in deciding which software will be best for your equipment based on their lifestyles and attitudes and habits towards computers. You can also check out websites that give online reviews about the best software in the market.

Make sure to look for software that is compatible with your machine’s operating system. Many software can work well for many operating systems, while others have specific operating system requirements. Having an antivirus firewall software that is not fully compatible with your computer will only cause you unnecessary expenses, even if the software claims to be the best among the pack.

Before deciding to purchase the most recommended antivirus firewall software, consider downloading a trial version from the software brand’s website. Most of these software makers offer one-month trial versions, and being a resourceful person that you are, doing so will buy you more time in carefully analyzing which software works best for your computer.

When buying an antivirus firewall software, prefer a kind that has optimum background security. This simply means that after installing the software, you will not always have to prompt it manually to scan and detect virus threats. Also opt for sophisticated and up-to-date software that can initiate and prompt automatic updates so you can ensure that you are always protected from the latest threats. More importantly, check software manuals and product information guides for certifications from standards setting organizations.

If you’re not a techie person, you might also want to prefer buying and installing an antivirus firewall software that is guaranteed user-friendly. Before installing your software, make sure that you have read and understood the manual very well. There’s no use purchasing software you will not be able to fully utilize in the long run if you don’t know how to apply its operating process. Not all antivirus firewall software available in the market today can guarantee 100 percent protection from online hazards and threats, but still, it’s wise to have one installed in your computer than not having any kind of protection at all.
