A computer virus is a type of malicious software program that can infect and damage computer systems. It is designed to spread from one computer to another and can be transmitted through email attachments, downloads, or other means.
When a computer is infected with a virus, the normal operation of the computer can be disrupted. Depending on the type of virus, it may slow down the computer's performance, cause programs to crash, delete files, or even render the computer completely unusable.
To protect against viruses, it is important to use up-to-date antivirus software and to be cautious when opening email attachments or downloading files from the internet. It is also recommended to keep software and operating systems updated to ensure they are protected against known vulnerabilities.
