How do I run a malware scan using built‑in Windows tools?

Introduction

In today’s digital age, safeguarding your computer against malware is more crucial than ever. Malware can compromise your sensitive information, slow down your system, and even lead to data loss. Fortunately, Windows provides built-in tools to help you run malware scans and keep your system secure. In this article, we’ll explore how to effectively run a malware scan using these tools.

Understanding Malware

Before diving into the scanning process, it’s essential to understand what malware is. Malware, short for malicious software, encompasses various harmful software types, including viruses, worms, trojans, ransomware, and spyware. Each type has its own method of operation and can severely impact your system’s performance and security.

The Importance of Regular Scans

Regular malware scans are vital for maintaining your computer’s health. Here are some reasons why:

• Prevention: Scanning regularly helps identify and eliminate threats before they can cause significant harm.
• Performance: Malware can slow down your computer. Regular scans ensure optimal performance.
• Data Protection: Keeping your data safe from unauthorized access is critical, and scans help in achieving this.

Windows Built-in Tools for Malware Scanning

Windows offers a couple of built-in tools for malware scanning: Windows Security (formerly Windows Defender) and the Offline scan feature. Let’s discuss how to utilize these tools effectively.

1. Windows Security

Windows Security is the primary tool for protecting your PC against malware. Here’s how to run a malware scan using Windows Security:
