WHAT IS A COMPUTER VIRUS
A computer virus is executable malicious software or code that self-reproduces by taking control over other programs on an infected computer. Designed to spread from one host computer to other computers, the computer virus is added to a software component or document and stays there until the user opens the file in question. When this happens, the virus will start executing its code and cause damage to the host computer.
There are many ways to contract a computer virus, with downloading files, email attachments, installing compromised software, or spamming links on social networks. You can spread the virus by sharing the infected files or links with others. If your computer is part of a network, with a single user opening the dangerous file on their desktop, it may be enough for the entire network to be compromised.
