What is it a computer virus?


Definition: A bug may be a malicious software program loaded onto a user’s computer without the user’s knowledge and performs malicious actions. In more technical terms, a computer virus is a type of malicious code or program written to alter the way a computer operates and is designed to spread from one computer to another. A virus operates by inserting or attaching itself to a legitimate program or document that supports macros in order to execute its code. In the process, a virus has the potential to cause unexpected or damaging effects, such as harming the system software by corrupting or destroying data.

 

Description: The term computer virus was first formally defined in 1983. Computer viruses never occur naturally. they're always induced by people. Once created and released, however, their diffusion isn't directly under human control. After entering a computer, an epidemic attaches itself to a different program in such how that execution of the host program triggers the action of the virus simultaneously. It can self-replicate, inserting itself onto other programs or files, infecting them within the process. Not all computer viruses are destructive though. However, most of them perform actions that are malicious in nature, like destroying data. Some viruses wreak havoc as soon as their code is executed, while others lie dormant until a specific event (as programmed) gets initiated, which causes their code to run within the computer. Viruses spread when the software or documents they get attached to are transferred from one computer to a different employing a network, a disk, file sharing methods, or through infected e-mail attachments. Some viruses use different stealth strategies to avoid their detection from anti-virus software. for instance, some can infect files without increasing their sizes, while others attempt to evade detection by killing the tasks related to the antivirus software before they will be detected. Some old viruses confirm that the "last modified" date of a number file stays an equivalent once they infect the file.

 

How does a computer virus attack?

Once a virus has gone through a program or file, the virus will lie until circumstances make the computer or device execute its code. In order for a virus to infect your computer, you have to run the infected program by yourself, which triggers virus code to be executed.

This means that a virus can remain lurking in quietness on your computer, without showing major signs. However, once the virus infects your computer, the virus can infect other devices on the same network. Stealing your secret data including passwords, logging keystrokes, corrupting files, spamming all your emails, and even taking over your machine are just some of the annoying things a virus can do.

While some viruses can just as playing in its effect, others can have damaging effects. This includes deleting data or causing permanent damage to your hard disk and other PC components. Worse yet, some viruses are designed with financial gains as a target.
