What Is a Computer Virus? 🦠 A computer virus is a type of malicious software designed to enter a computer or other digital device and cause unwanted or harmful activities. Just like a biological virus can spread from one person to another, a computer virus can spread from one computer or file to another. Computer viruses are created by cybercriminals or other individuals for different purposes. Some viruses are designed to damage files, slow down computers, steal information, or interfere with normal computer operations. How Does a Computer Virus Work? A computer virus usually needs a host file or program to spread. When an infected file or program is opened, the virus can become active and begin performing its malicious activities. For example, a person might download an infected file from an unsafe website or receive an infected attachment through email. Once the file is opened, the virus may start spreading to other files on the device. Some viruses can also spre...

What Is Phishing and How Does It Work? Phishing is one of the most common cybersecurity threats on the internet. It is a type of online scam where criminals try to trick people into revealing sensitive information such as passwords, bank details, credit card numbers, or account login information.

What Is Two-Factor Authentication (2FA) and How Does It Work? In today’s digital world, protecting your online accounts is more important than ever. Many people use passwords to protect their email, social media, banking, and other online accounts. However, passwords can sometimes be stolen, guessed, or exposed in data breaches. This is where two-factor authentication (2FA) becomes useful. What Is Two-Factor Authentication? Two-factor authentication, commonly called 2FA , is a security method that requires two different forms of verification before you can access an account. Instead of relying only on your password, 2FA adds another security step. Even if someone gets your password, they may still be unable to access your account without the second verification method. For example, when you sign in to an account, you may first enter your password. The service may then ask you to enter a six-digit code sent to your phone or generated by an authentication app. You must ...

What Is a Firewall and How Does It Work? In today’s digital world, protecting computers, smartphones, networks, and other devices from online threats is extremely important. Every time a device connects to the internet, it can potentially communicate with other systems. Some of those connections may be unsafe or unwanted. A firewall helps protect devices and networks by monitoring and controlling network traffic. What Is a Firewall? A firewall is a security system that controls incoming and outgoing network traffic based on a set of security rules. It acts like a barrier between a trusted network or device and potentially unsafe networks, such as the public internet. The main purpose of a firewall is to prevent unauthorized connections while allowing legitimate traffic to pass through. For example, when you visit a website, your device sends and receives data through the internet. A firewall can examine that network traffic and determine whether it should be allowed or blocked ac...
