How do computer viruses work?

A computer virus is a small piece of software that can copy itself and corrupt your computer. Viruses often spread by sharing infected files or attachments, or by opening infected email attachments.

Some viruses are designed to damage the computer by deleting files, corrupting data, or damaging hardware. Others are designed to steal sensitive information, like passwords or credit card numbers. Some viruses can do both.

Most viruses are spread by people who are unaware that their computer is infected. Once a virus is on your computer, it can do a lot of damage quickly. That’s why it’s important to have virus protection and to keep your operating system and software up to date.

How do computer viruses work?

Generally, a virus is a code which is capable of copying itself and typically has a detrimental effect, such as corrupting system files, stealing personal information or displaying unwanted advertising.

A virus must be able to attach itself to another piece of software in order to spread – this is usually done by modifying an existing file or program, or by creating a new file or program. Once a virus has attached itself to another program, it will activate when that program is run.

In order to avoid detection, a virus will often try to disguise itself as another file or program – for example, by changing its icon or file name. Some viruses will even fake the results of a scan in order to trick you into thinking your computer is clean.

Once a virus has infected your computer, it can start to replicate itself and spread to other computers. It can also perform malicious actions, such as deleting files, encrypting files (making them unreadable), or stealing personal information.
