FAQ About Understanding the Basics of Cybersecurity

What is a virus?

In the context of computer security, a virus is a type of malicious software (malware) that can replicate itself and infect other files and programs on a computer system without the user's knowledge or consent.

Like a biological virus, computer viruses spread from one system to another and can cause damage to the system or its data. They can be spread through a variety of means, including email attachments, infected software downloads, and malicious websites.

Once a virus infects a system, it can perform a wide range of malicious actions, such as corrupting or deleting files, stealing personal information, or hijacking the system for use in a botnet.

Protecting against viruses requires a combination of prevention, detection, and response. Prevention measures include keeping software and operating systems up to date with security patches, avoiding suspicious emails or downloads, and using antivirus or anti-malware software. Detection measures include monitoring system logs and network traffic for signs of suspicious activity, while response measures include isolating infected systems and restoring backups in the event of an attack.
