Source code viruses attack computer code, rendering programs unusable or generating errors. They are rare but can be difficult to combat as the source code is often not human-readable. Programmers need skill to develop them, and users can contract them through connected networks. Antivirus software can limit the risk of infection.
A source code virus is a computer virus that attacks source code to corrupt it in some way. It can render a program or an operating system unusable, hijack a machine for a certain purpose or generate errors in the system. Viruses of this nature are relatively rare, but can be found in the wild and are sometimes difficult to combat because the source code is often not human readable and therefore can be difficult to fix.
Source code provides the basis of programs, applications and operating systems. Viruses themselves are programs or pieces of code that infect computers, usually with a malicious purpose such as disruption of service or compromise of confidential material. In the case of a source code virus, the virus attacks the source code of one or more computer components, rather than running it as its own program.
Programmers need a reasonable level of skill to develop a source code virus because they need to be able to alter source code. This requires knowledge of programming languages and the ways they can be manipulated to achieve various goals, such as making an operating system impossible to boot. Virus designers may look for programs with vulnerable source code, which requires the ability to examine and understand the raw code behind various computer programs. Some programmers rely on virus fabrication kits or code published by more experienced programmers to create their viruses.
The user can contract a source code virus through a variety of means. When viruses enter connected networks, they can also spread to other computers in the system. This can result in the destruction of an entire network and hours of work for technicians to find and eradicate the virus. In this case, the technicians must eliminate the source code virus and repair the damage left behind, if possible. This may require a fresh install to get rid of the contaminated source code.
Antivirus companies regularly scan the Internet for emerging viruses and use user reports to build a library of known viruses and ways to combat them. Users can limit the risk of viral infection by maintaining such software and keeping it active at all times. It is important that your software is up to date, as some viruses mutate rapidly and new versions are constantly being released. A user with an outdated virus library may be vulnerable to a new virus that could cause considerable damage.
