Need For A New Anti-Virus Model

This is the second in a series of articles highlighting reasons why we need a new model for anti-virus and security solutions.
Reason #1: the Basic Model
Anti-virus software vendors still rely on yesterday's methods for solving today's problems: they wait for the next virus to wreak havoc and then produce a solution. That worked for a long time when a virus would take years to traverse the world. But in this fast-paced Interet-crazed world we live in today, this type of solution is no longer applicable. Now a virus can traverse the world and infect millions of computers in minutes.
In the good old days a virus traveled by floppy disk. Put a floppy in your computer and save some data to it and the virus would infect the floppy. Then unwittingly put the infected floppy in another computer and presto the new computer would become infected. (I'm skimming over a lot of detail here to make a point). So the virus' progress was slow and steady. Anti-virus vendors had time on their side. They had the time to get a copy of the virus, dissect it, run it through a series of tests to come up with a signature string (see below for definition), put the string into a database of strings to search for when scanning your hard drive (and floppies) and release the new database to the public. Ten years ago this system worked very well.
But now everyone is connected via the Internet. Now, using email as a transport point, it doesn't take years to gather momentum, instead it takes a matter of minutes. And here is where the model breaks. Step back and ask yourself the following question: if vendors can catch known and unknown viruses as their literature states, how then is it that we continue to have virus problems?
The answer lies in the fact that virus authors have been more creative in coming up with new ways to infect and wreak havoc and the software industry has not responded in kind, preferring to stay embedded in its old fashioned methodologies.
Why don't the old ways work any more, you might ask? It's relatively simple. Let's go through the steps.
A virus author unleashes NewVirus via email. He mass mails his virus to thousands of people. Some, not all, unwittingly open the attachment thinking it's from a friend or the subject is so enticing that they are fooled into opening it without thinking it's a problem (cf. nude pictures of Anna Kournikova). The email attachment immediately starts emailing everyone in his contact list and embeds itself into his operating system so that it's activated every time he turns on his computer.
The folks he emails in turn get fooled into thinking the email is valid and they open the attachment. Very quickly all hell breaks loose. Agencies which monitor Internet traffic see problems arising with the sudden spikes in email traffic and they begin to get calls or emails alerting them to the fact that there's a new problem. Samples are obtained and sent off to anti-virus vendors. They pass the emails through a series of tests to analyze what exactly the virus does and how it does it. Additionally analysis is performed to extract a unique string of 1's and 0's to identify this attachment as none other than NewVirus. This is called the signature string. It's important that whatever string is arrived at does not exist in any other program or piece of software; otherwise, you will get what is commonly called a false positive.
Quick digression on false positives if a vendor arrives at a unique string that just happens to be embedded in Microsoft Word, then every time a user runs a scan of their hard drive, Microsoft Word will be identified as being infected with NewVirus. Users will uninstall Word and re-install only to learn that they are still infected. There will be complaints; the vendor will be forced to re-assess the signature string and re-release his list of strings and admit the error.
Typically signature strings are matched against a whole boatload of commonplace software just to protect against this occurrence, but it still happens and vendors learn to add new software to their test beds.
OK, so the vendor has arrived at a signature string. Next? Implement the string into their string database so that when their scanners are scanning they will match what's on your hard drive to what's in the database. After the database has been updated they release the database to their customers in what's commonly called a push where they send the updates to their primary users.
If you did not buy into this service, you must know enough to log into your anti-virus vendor and update your software so that you stay current.
So where are we? The bad guy or problem teenager- has unleashed NewVirus. NewVirus has infected thousands of computers; vendors have been alerted; NewVirus continues to infect; solutions are achieved and pushed to corporate clients; NewVirus continues to infect hundreds and thousands of computers; corporate clients breathe a sigh of relief and alert their users as to the new threat.
Thousands, if not millions, of computers become infected and need to be cleaned because the best way to solve the virus problem is to wait for each new virus to come along and solve on a case by case basis.
But if you sat back and said: what if? What if you categorized all the things a virus can do (or could do), built a series of computers to allow any email attachment or program to have full rein of a computer (much like it would have on your own computer such a computer is called 'honeypot') and then analyze that computer for unwelcome behavior?
That would be a true pre-emptive strike against all malicious software. This is the behavior-based model. Such a model would actually protect you unknown viruses, along with all the known 70,000 viruses.
In part 2 we'll discuss the risks and security failures of having distributed vendor software on your desktop.

The Creeper and The First Anti-virus Program

It is generally believed that the first computer virus to be unleashed on vulnerable computers was the Creeper Virus. The Creeper Virus infected the forerunner to the internet, a computer network called ARPANET. This was back in the early 1970s. The virus was non malicious in that it did not harm the computers it affected, however on infected machines it displayed the message 'I'M THE CREEPER : CATCH ME IF YOU CAN.'The Creeper was duly caught by what is undoubtedly the first piece of antivirus software ever created. This programme was called the Reaper (as in Grim Reaper) and it sought out computers infected with the Creeper and duly destroyed it. The Reaper programme was not like the anti-virus programs we know today, but in fact was a virus itself in that it was self replicating and spread through a network. (About a year ago we discovered biological viruses that can infect other biological viruses.)T

here are a great many rumours concerning the authors of both The Creeper and The Reaper, and many suspect that it was the same person. His (or her) motivations have been analysed as possibly a joke, a scientific experiment that got out of hand, and even blackmail. Whoever it was managed to keep it away from the general public, which is remarkable in itself.An alternative possibility is that it was not done by one person. There was considerable military involvement in the ARPANET network and one aspect of the research into ARPANET was to examine whether the system was sufficiently robust to withstand a nuclear war and still provide a communications network. Both The Creeper and The Reaper could have been military experiments to test network vulnerability and protection. This would certainly explain why the identity of the creator has never leaked out.Ever since that first battle between virus and virus destroyer there has been a continual war waged between an ever increasing army of viruses and ever more sophisticated antivirus software. There are so many viruses and other malware lurking in hidden corners of the internet that to run a computer without adequate protection would be foolhardy.

Software - Advantage And Disadvantages Of Free Antivirus Software

The anti virus software market for the most part has been a thriving one. With new viruses coming up everyday, anti virus software companies were always assured of good revenues.

But things started changing with the advent of free anti virus software. Given free anti virus software may not be as good as their commercial counterparts but they nevertheless, are pretty good for most computer users. Most free anti virus software come with even advanced detection technologies. What’s more, these free anti virus software keep their virus signature database updated regularly like any other commercial anti virus software!

Many people are of the opinion that commercial anti virus software are rip-offs. Most of them require renewal of licenses every year by asking a user to pay certain amount of money. If licenses are not renewed, such commercial anti virus software would stop detecting newer viruses. Free anti virus software, however, does not require such renewal of licenses. They are free to download, install, run and update as and when necessary.

One of the most popular free anti virus software is Grisoft’s AVG anti virus software. This free anti virus software is as good as a free software can get. There are no hidden malware and neither does one have to pay anything for using it. The virus signature database can also be updated without paying a fee! Unfortunately, this free version is however, meant for personal and non-commercial use only.

There are many other free anti virus software out there. Not all of them are however, good enough to provide proper security to computers. Some free anti virus software do not come with advanced detection technologies and therefore, may fail to detect different variants of viruses. Such free anti virus software are not simply worth anything. If you are planning to get a free anti virus, it is important you do some homework on the software. Check the reviews of other users to find out how good, in reality, the free anti virus software is before you start trusting it wholeheartedly!

Antivirus Computer Software - Safeguard Your Personal Computer From Dangerous Viruses

Before a discussion of antivirus software can begin, it is important to know what a virus is. The virus we are talking about here is not the medical virus that can spread from one person to another, but a virus for a computer. It is funny because both types of these viruses have some similar properties in that computer viruses are contagious, and spread and infect other computers very quickly like human viruses. They are very common and most people have had the unpleasant experience of a computer virus just like the medical virus. In most cases a computer virus is a executable code. They are designed to create problems on the affected computer. You will know if you have a computer virus very quickly, because nothing will function as it should. If other computers are connected to this machine by network or email, the virus can be spread very quickly because the virus replicates itself to enter and infect these computers.These viruses do basically three types of damage to the computer it affects. First is trojans or worms which are designed to steal important personal information such as your ID's, passwords, account numbers, and other personal information found on your computer. Another type is designed to gain access to your machine and then hijack it.

Once it has control of the affected computer a hacker can use it for malicious purposes or as a spam machine to send thousands of unwanted emails. The last type is sometimes referred to as macro viruses. This type of virus is designed so they can delete or overwrite the system or data files on the affected computer. This causes the computer to crash and become unbootable or non operable. Many of the computers that get this type of virus have a crashed hard drive which is not repairable and all your data is lost permanently.Now the best way to combat these infections is installing antivirus software. Some well known antivirus programs are Norton or Symantec, McAfee and Trend Micro. Good antivirus software comes with features like a built-in firewall and usually offers an access to online data backup. This antivirus software have the option to deactivate the malicious viruses. This antivirus software protects your computer from virus attacks in three main methods. The first method is prevention which involves detecting and eliminating new viruses from your computer.

They get the latest virus definitions from their server so the know what to look for and protect against. The second method is cleaning infected computers. This involves detection and extermination of the virus, along with repairing the damaged files. The last method is protecting your computer by monitoring emails, downloads and protection while internet surfing. Also this method regularly scans your computer or a preset scheduler to keep you virus free.Antivirus software is very effective in finding and deleting harmful computer viruses. Even so, computer users should follow some safety rules to stiffen protection even more:

Do not open unsolicited e-mails. A lot of people tend to open unsolicited e-mail containing viruses, either unknowingly or absent-mindedly. A good rule of thumb is to never open emails from people you don't know.

Never download an attachment to an email without scanning it for viruses first. Even if you are sure of the source and what it contains, it is always better to scan it before downloading.

Make sure you also use a firewall.

Don't download free software or music. When you do this you are just asking for trouble. So avoid this as much as possible.

Don't use free antivirus software. They don't work very well at all. Buy I good one and remember you get what you pay for.

Search on internet for antivirus reviews and research yourself for best antivirus software.

Best Antivirus for 2011

Hardly anyone ever sees the classic "Virus" now days. Spyware and Trojans are way bigger threat today. Therefore, criteria's by which antivirus software and security suites should be measured have also been changed. Some while ago, we developed the point of view about the word Antivirus in general, when we say Antivirus we refer to a software that protects PC from all kinds of threats, against Virus, Spyware, rootkits and Adware, Trojans and all the other malware as well as Identity Theft and Phishing. Modern Antivirus should be able to handle all the threats listed above.Before answering the question what is the best Antivirus for 2011, there is a question, which of these two should we use; Standalone Antivirus or the whole Security Suite. 5-6 years ago definition of Security Suite was different than it is today. Back then, when software included firewall, people used to refer it as Security Suite, but that has changed now. Modern Security Suites include far more than firewalls: full Security Suites have many features such as Parental Control, Site Adviser, Spam Protection and email Protection, Identity Theft protection, Anti Spyware and many other features, also some Security Suites include utilities such as personal data encryption, data shredders, back-up utilities and rescue disks. So when it's about choosing between Security Suites and Standalone Antivirus, it's really up to you, to make a choice, first of all you need to consider which of those features you may find useful.Competition between Antivirus vendors largely depends on which Antivirus includes more features for standalone product.To answer the question what is the best Antivirus for 2011, let's make a quick reviews of several leading Antivirus software products:

Trend Micro Titanium Antivirus Plus 2011:

To make it simple, this particular Antivirus is easiest to use Antivirus on the market today. In fact it's ridiculously easy, considering there are only 3 buttons on the main interface. Well surely modifying settings is possible if needed but the engineers made sure you won't be spending much dealing with settings. So, there are Scan, Options and Statistics buttons. Trend Micro Titanium Antivirus Plus 2011 largely depends on Internet Connection rather than your system, which is good since the Antivirus Engine hardly, uses the system resources. Even the installation process is extremely fast. It really does take less than a couple of minutes. When it comes to detection, Trend Micro shows fairly good results.

Norton Antivirus 2011:

Even though Norton 2011 standalone doesn't include full firewall features, Antivirus itself with new Reputation scan system shows remarkable results, Reputation Scan is designed to reduce Scan time by skipping the files Norton has previously determined cannot be infected. Norton AV 2011 also includes unique feature to protect against Facebook threats. Truth is, This Antivirus has already won many rewards in this year; its fast, and its reliable. 

Bit Defender Antivirus 2011:

This Antivirus in standalone version includes almost equal amount of features than some of the other Security Suites. While some people may find the interface a bit confusing, BitDefender does the job well.

So, what is the Best Antivirus for 2011? It's hard to say, all the products have pros and cons. Which Antivirus you should go for, entirely depends on your needs and your hardware and area of use. Kaspersky, AVG and Avast Antiviruses also show good results in detection, scan time features. For home use and relatively slow computers I recommend Trend Micro Titanium Antivirus Plus 2011. for advanced users who do a lot of browsing, Norton Antivirus 2011 is a good choice. If you are going for free antivirus there is no alternative to AVG Antivirus Free edition.
