Kinds of AntiVirus

Antivirus is a type of software that is used to detect and remove computer 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, the software running in the background (background) and scanning of all files that are accessed (opened, modified, or when stored). Most of the antivirus to work with several methods such as below:
search using the database of virus signatures (virus signature database): How is this approach which is widely used by traditional anti-virus, seeking signs of the presence of the virus by using a small portion of the virus code that has been analyzed by antivirus vendor, and has classified according to the type, size, power smash and some other categories. This can be calculated fast and reliable to detect the virus-the virus that has been analyzed by antivirus vendors, but can not detect the new virus until the virus signature database is installed in the new system. The database of virus signatures can be obtained from the antivirus vendor, and generally can be obtained for free via download or via subscription (subscription).
Pendeteksian to see how the virus works: How it works is like this antiviral approach that borrowed from the new technology that is applied in the Intrusion Detection System (IDS). This is often referred to as Behavior-blocking detection. How to use this policy (policy) that should be applied to detect the presence of a virus. If there is software that behavior "not reasonable" according to the policy that is applied, as well as the software tries to access the address book to send e-mail in bulk to the list of e-mail that is in the address book is (this is often used by virus to transmit the virus through e-mail), then the antivirus will stop the process undertaken by the software. Antivirus can also isolate codes suspected virus as administrator to determine what to do next. The advantage of this is how antivirus can detect the new virus-the virus that has not been recognized by the virus signature database. Weakness, clear way to monitor the antivirus software business as a whole (not the monitor), it often makes anti-virus false alarm or "False Alarm" (if the antivirus configuration too "loud"), or even allow the virus to breed in the system (if antivirus configuration too "soft"), false positive occurred. Some manufacturers call this technique as a heuristic scanning.
Antivirus which uses behavior-blocking detection is still a little amount, but in the future, most likely all use antivirus akan this way. Some anti-virus also use two methods on the same time.
