In the present generation, computer and internet have become a necessity. When the internet is used on a daily basis, there is no doubt that the individual would be receiving pop- ups and spam mails regarding antivirus protection and spy-ware. The main aim behind this is to protect the computer from unwanted viruses that may attack the system. Viruses are dangerous and hence there is no doubt that the computer needs protection from them.

A computer virus is one among the programs that are known as Maliceware. This is an application that is designed to steal, damage or delete the information. It has the capability to also hijack the PC and destroy the hardware of the computer. The other two types of maliceware along with virus are worms and Trojans. Hence most of the antivirus programs that are designed help in detecting these threats and treating them.

Thanks to the growth in technology, the viruses can spread around the world in a few minutes thereby affecting the unprepared and unprotected users. As this happens in a very few minutes, the need for an antivirus protection increases drastically. These antivirus programs make use of two very common approaches to detect the threats from the system. One of the very common methods is the signature detection through which the threats from the drives, computer and the storage devices are found out with the help of a code. However this type of a program requires the founder to obtain the copy of a virus and at the same time a reverse engineer who would help in obtaining markers concerned with the programming. It is after this process that through updates the markers are loaded into the software. This methodology of \”Signature Detection\” is very useful for the detection and protection of the system against the viruses but it is certainly not useful if the virus has no definition.

Another very common antivirus application is “Activity”. It will look into the computer for any suspicious behaviour such as modifications of any file or folder and unauthorized connections. The antivirus protections that have the potential to scan the system for the latest viruses are better at detecting even the latest threats. However most of the antivirus programs are a combination of virus activity and signature detection.

There are many antivirus products and programs that are available in the market and if you are deciding to choose one, then it is a tough decision. Depending on whether the program is required for home or business, the antivirus solution has to be chosen. There are viruses that affect the system on a daily basis and hence you have to make sure you choose the best antivirus program that can update on a regular basis so that the viruses are cleaned up regularly. This is the need of the hour too. Hence the main concern for the buyer should be whether the antivirus software can release relevant updates at the time of need. If there are not proper updates, then it would be dangerous. The prices of the various programs differ and they can be purchased from any of computer stores across the world. Some of them are available online but the major decision to make is the software that has to be purchased.
