1. Understand What Malware Is

Before you can combat malware, it’s essential to understand what it is:

Definition: Malware, or malicious software, refers to any program designed to harm, exploit, or otherwise compromise a device or network.
Types of Malware: Common types include viruses, worms, trojans, ransomware, spyware, and adware, each with distinct behaviors and impacts.

Frequent Crashes: Regular crashes or unexpected shutdowns can indicate underlying malware issues.
Unwanted Pop-ups: An increase in intrusive pop-up ads, especially those that appear even when your browser is closed, is a strong indication of adware.
Unknown Programs: Discovering unfamiliar applications or toolbars installed on your device is a red flag.
Unauthorized Access: If you notice unusual account activity, such as login attempts from unfamiliar locations, your device may be compromised.

3. Run Antivirus and Antimalware Scans
