Method of Choosing a Good Antivirus

Method of Choosing a Good Antivirus

Technology has been increasingly developing world today. In this fast-paced world, of course in addition there is the positive side there is also a negative side (the positive side all already know). Well one of the negative side of IT development is the increasingly rapid spread of the virus. The virus has developed into one of the most dangerous weapon in the computer world. For more details about computer viruses, please read my article What Is a Computer Virus. Now to cope with these viruses, we need a reliable antivirus program. Still, the antivirus is not one hundred percent capable of protecting the computer. Now, through this article I hope you can choose antivirus suit your needs.

A. What Antivirus That? Before choosing antivirus is good that we know little about the antivirus. Antivirus software is befungsi to detect, remove and quarantine viruses from computer systems. Also called Virus Protection Software. This application can determine whether a computer system has been infected with a virus or not. Generally, this software runs in the background (background) and do a scan of all files that are accessed (opened, modified, or when stored). With earlier explanation would arise the question how to choose the best antivirus? Here I am trying to wrap up a barometer of what is used in choosing antivirus products. B. What Being a Priority in Determining Quality Antivirus Products? Now there are dozens of surveys conducted in various antivirus products. From the survey results, then found a reference in selecting antiviral priorities include:

   1. Detection Rate Test
      It is a test of antivirus signature base of thousands and even millions of virus samples, and then compare Which most antivirus detects the virus samples.
   2. Heuristic / Prospective / Generic Test
      It is a test virus / new malware that does not exist in the database (signature file), but use it as a reference signature database to detect virus / malware new, if there are characteristics of the virus / malware then the heuristic function will mendeteksinya.Dalam this is like DNA in humans, for example, Peter Parker is a virus and has existed in an anti-virus signature database, so it can detect that this is a virus, but when Peter Parker then transformed into Spiderman, then the basic antivirus signature database does not recognize that this virus / malware, but the heuristic function will see that the DNA of Peter Parker and Spiderman are the same, then the antivirus will detect that this is a virus / malware.
      So the heuristic function is very important after Signature Database.
   3. Performance Test
      Use antivirus course will take a computer resource, such as CPU, Memory, our role here is to be smart in choosing antivirus products that have well-resourced settings, so as not to disturb the performance of this komputer.Saat, there are many antivirus software that uses multiple engines in their products , some use 2 (two) engines, or even a 7 (seven) engine, where it would interfere with the performance of computers, resources / resources will be widely used computers compared with only 1 (one) engine, among others:
      - Gdata: 2 Engines (Bitdefender engine hire & Avast)
      - Trusport: 3 Engines (renting engines: AVG, Norman and Dr.Web)

C. Organization / Agency Which Is Becoming Independent References in Antivirus Product Comparison Doing? To conduct surveys and conclude a variety of data about the antivirus, of course requires a professional independent agency. Currently there are about 22 agencies / non-profit organization that discusses and perform comparative antivirus products, but there are only about 5 trusted organization / indenpenden based surveys, which can be ascertained there are no sponsored links in it, among others:

    * AV-Comparatives
    * Virus Bulletin / AV-Test
    * ICSA Labs / West Coast Labs
AV-Comparatives has by far the highest rating as an independent entity conduct comparative antivirus product, and always get a very positive response from the public of any reviews that publish, VirusBulletin and AV-Test evaluated the same in the second, also ICSALabs and WestCoastLabs on third, this independent body requires minimum conditions and requirements of the antivirus vendors whose products will be on the test. In addition, here is excluded from the analysis of Gartner, Gartner analyzed considering the many products and not specific to the antivirus only. Independence of the AV-Comparatives can be seen from the assessment of 4 (four) years for the category of "Product of the Year":

    * Year 2007: Eset NOD32
    * Year 2008: Avira
    * Year 2009: Kaspersky
    * Year 2010: F-Secure
Where there is no one brand has ever ranked "Product Of the Year" in a row, so in this article that will be discussed is a test from AV-Comparatives. D. Testing / Testing by AV-Comparatives Testing by AV-Comparatives conducted periodically by 3 (three) months that includes: Restropective / Proactive Test and On Demand Comparative, where we can not be guided only by one test, given the consistency of a product should be seen within a specified period.

Detection Rate Each test result can be seen in the Result Summary page The following recapitulation of the AV-Comparatives results from February 2007 to November 2010, until this article was made there has been no report of new testing.
From the above conclusion, that in determining the quality of the best antivirus products on the basis of priority are:

   1. Detection Rate Test
   2. Heuristic / proactive / Prospective Test
   3. Performance Test
And in determining the quality of the best antivirus products should be viewed from several times of testing, so that we can see a product that is perfectly consistent with the quality. Well, good choice! Make sure you do not install two antivirus on one computer, because it can collide and slow down your computer system.
