What is Antivirus Software?

Antivirus software is a program designed to detect, prevent, and remove malicious software, or malware, from your computer. Think of it as a security guard for your digital life. It watches over your system, ensuring that harmful files don’t make their way in.
There are various types of malware, including:

- Spyware: This secretly gathers user information.

2. Heuristic-Based Detection
Heuristic detection predicts future threats by analyzing the behavior of programs. It looks for suspicious activity, even if it doesnt have a signature. Imagine spotting a thief working on a heist. You might not recognize the thief, but you can tell something isn’t right.
3. Behavioral-Based Detection
This method observes how programs behave while they run. If a program starts acting like malwarelike trying to access sensitive data without permissionthe antivirus can intervene. it’s like having a friend who knows your habits and can tell when something feels off.
