Adware is unwanted software that displays ads on your computer or browser, often slowing down your system and tracking your online activity. In this detailed guide, you’ll learn what adware is, how it infects your device, and how to safely remove it from both Windows and Mac computers. Whether you’re a beginner or more experienced user, these steps will help you regain control over your device.
What Is Adware and Why It Matters
Adware is a type of potentially unwanted program (PUP) that displays advertisements or redirects your browsing to sponsored sites. Some adware is bundled with free software installers, while others can be installed unknowingly when users click misleading ads.
Common adware symptoms include:
- Frequent pop‑ups and banners
- Browser redirects to unknown search engines
- New toolbars or extensions you didn’t install
- Slower system performance
- Unwanted notifications or ads outside of the browser
Adware can also collect basic browsing data, which can feel invasive even if it’s not classified as high‑risk malware. That’s why removal and prevention are important for privacy and performance.
