A computer virus, like a flu virus, is designed to spread from host to host and has the ability to replicate itself. Similarly, in the same way that influenza viruses can not be reproduced without a host cell, computer viruses can not be reproduced and broadcast without the programming as a file or a document.
In more technical terms, a computer virus is a type of code or malicious program written to alter the functioning of a computer and is designed to extend from one computer to another. A virus works by inserting or attaching to a legitimate program or document that supports macros to execute its code. In the process, a virus can cause unexpected or harmful effects, such as harming the system's software by corrupting or destroying data.
How is a computer virus attacked?
Once the virus has successfully hit a program, file or document, the virus will remain latent until the circumstances make the computer or device execute its code. In order for a virus to infect your computer, you must run the infected program, which in turn causes the virus code to run.
This means that a virus may remain inactive on your computer, without presenting signs or significant symptoms. However, once the virus infects your computer, the virus can infect other computers on the same network. Stealing passwords or data, registering keystrokes, corrupting files, spamming email contacts and even taking care of your machine are just some of the devastating and irritating things that can cause a virus.
While some viruses may be fun with intent and effect, others may have profound and harmful effects. It includes erasing data or causing permanent damage to your hard drive. Even worse, some viruses are designed taking into account financial gains.
How do computer viruses spread?
In a constantly connected world, you can hire a computer virus in many ways, some more obvious than others. Viruses can be spread through attachments of emails and text messages, Internet file downloads and social media scams links. Your mobile devices and smartphones can be infected with mobile viruses by downloading shady applications. Viruses can be hidden in disguised as attachments of socially shared content such as fun images, greeting cards, or audio and video files.
