Understanding Adware: How to Identify and Prevent It

 Adware

Adware is malware that displays advertisements on a computer or device without the user's knowledge or consent. Adware can also collect information about a user's browsing habits and online behavior to target them with customized ads.

Adware can be installed unknowingly when a user is trying to install legitimate applications with which adware is bundled. It can also be downloaded through mobile apps or by downloading freeware like toolbars, HD wallpapers, or widgets.

Some signs of adware include:

  • Advertisements appearing in places they shouldn't be
  • The web browser's homepage changing without permission
  • Web pages not displaying properly
  • Website links redirecting to different sites
  • The web browser slowing down
  • New toolbars, extensions, or plugins appearing in the browser

To prevent adware, you can use antivirus software or regularly update your device. Antivirus software can detect malware before it infects the rest of your device.
