A virus is software designed to replicate itself and spread from one device to another, often with the intention of causing harm or disruption. Viruses are often transmitted through email attachments, downloads or other means and can have a variety of negative effects on a device or network, such as slowing down performance, stealing personal data or displaying unwanted advertisements.
When a virus infects a device, it can replicate and spread to other devices on the same network or to other networks via the Internet. Some viruses are designed to damage or delete files, while others can be used to steal personal data or take control of a device for malicious purposes.
To protect yourself from viruses, it is important to use anti-virus software and be careful when opening email attachments or downloading files from the internet. It is also a good idea to keep your operating system and other software up to date, as these updates often contain security patches that can protect against viruses and other threats.
