Retrovirus is a type of computer virus that is self-replicating and able to spread to other computers. It achieves this by inserting its own code into other programs and data files, which then copies itself onto new systems when executed. It is named after the retrovirus, a type of virus found in nature that copies its genetic material into host cells in order to replicate itself. With the rise of computers and the accompanying technology, use of retroviruses to create malicious software has become commonplace in modern computing.
Retroviruses may be spread via a variety of methods, such as file exchange, diskette, or email. Other methods may include downloads from malicious websites, email attachments, or even CDs or DVDs. Outdated or vulnerable computer systems are especially prone to being infected with a retrovirus.
Under normal circumstances, the spread of a retrovirus is stopped either by antivirus software or by other preventative measures. An antivirus program works by scanning an infected system and attempting to stop the infection. Other methods of blocking or preventing retrovirus infections include authenticating downloaded programs, limiting executable code, and keeping software up to date.
Retrovirology is the study of retroviruses, their ecology, and their potential to cause harm. Such research involves the examination of the genetic structure of the virus, and the development of methods to detect and prevent infection. The ultimate goal of retrovirology is to create and introduce effective treatments, vaccines, or antibodies for infection with retroviruses.
Over the years, numerous antivirus programs have been created with the aim of combating retrovirus infections. Some of the most popular programs include McAfee, AVG, Avast, Norton, and Symantec. These programs may be purchased and downloaded from the Internet, allowing users to protect their systems against retroviruses.
