Virus

Virus.

       Virus is a self replicating program that it produces its own copy. These viruses can be executed as soon as they are downloaded, it may wait for the host to execute them.

Characteristics of Viruses.

          There are some characteristics of viruses. These are as follows.

Infecting other files

Alteration of data

Transformation

Encryption

Self-Replication

Corrupt Files and Program

Ways of infection.

            Virus infects system by different ways. These ways are as follows.

Email Attachment

File Download

Infected Disk

Stages of Virus Life.

           The process of developing a virus till its detection is divided into six stages. These stages include the creating of virus, its execution, detection, and anti-virus stages. The stages of developing a virus are as follows.

Design.

           In designing phase, Virus is created. To design a virus, the developer can create its own virus code completely from scratch using programming languages.

Replication.

           In this phase when virus is deployed,the virus replicates for a certain time period in a target system. After a certain time period, virus will spread itself.

Launch.

           Launch stage is a stage when user accidentally launches the infected program. Once the virus is launch, it starts performing the action that is programmed in it.

Detection.

           In detection phase, the behavior of virus is observed, and the virus is identified as potential threat to systems. The developers of antivirus observer the behavior of reported virus.

Incorporation.

          Anti-Virus Software developer after identification, detection and observing the behavior of virus, design a defensive code in term of anti-virus or an update to provide help and support to an older version of anti-virus to detect this new type of virus.

Elimination.

          By installing the update of anti-virus or downloading the newer version of anti-virus users are capable of detecting advanced threats that can eliminate the threat from its operating system.
