How to Get Rid of Adware on Your Computer

Adware, short for advertising-supported software, is a persistent nuisance that plagues many computer users. It sneaks onto your device, bombards you with unwanted advertisements, and can compromise your privacy and security. Fortunately, there are steps you can take to effectively remove adware from your computer and prevent future infestations.

How Does Adware Function?

Adware operates by integrating itself into legitimate software or disguising as harmless applications. Once it infiltrates your system, it displays intrusive advertisements in various forms, such as pop-ups, banners, and even browser redirects. Adware often relies on tracking technologies to gather information about your browsing habits and preferences, allowing advertisers to target you with more specific ads.

How to Detect the Presence of Adware:

  1. Unwanted Advertisements: The most obvious sign of adware is the sudden appearance of excessive and intrusive advertisements, even when you're not browsing the internet.

  2. Browser Modifications: Adware may alter your browser's homepage, search engine, or new tab settings without your permission.

  3. Sluggish Performance: If your computer slows down significantly, adware might be consuming system resources to display ads.

  4. Unknown Browser Extensions: Check your browser's extensions or add-ons for any unfamiliar or suspicious entries.

What Makes Adware Harmful?

Adware is more than just an annoyance. It can have harmful implications for your computer and online security:

  1. Privacy Intrusion: Adware collects your browsing data, which could include sensitive information like passwords, credit card details, and personal preferences.

  2. Malware Delivery: Some adware might act as a gateway for more malicious software, like spyware, ransomware, or trojans.

  3. Resource Drain: Adware can consume your device's resources, leading to sluggish performance and reduced battery life.

  4. Network Congestion: The constant display of ads can consume your internet bandwidth, causing slower internet speeds.

How to Get Rid of Adware:

The process of removing adware depends on your operating system and browser. Here's a step-by-step guide for common platforms:

  1. MacOS: a. Close all open applications. b. Go to the "Applications" folder and uninstall any suspicious or unfamiliar software. c. Reset your browsers to their default settings. d. Install reputable anti-malware software and perform a scan.

  2. Windows: a. Use the "Add or Remove Programs" feature to uninstall suspicious applications. b. Reset your browsers to their default settings. c. Run a full system scan with reliable anti-malware software.

  3. Safari: a. Open Safari and go to the "Safari" menu. b. Select "Preferences" and navigate to the "Extensions" tab. c. Remove any unwanted extensions. d. Clear your browsing history and website data.

  4. Mozilla Firefox: a. Click on the menu icon and select "Add-ons." b. Go to the "Extensions" tab and remove suspicious add-ons. c. Reset Firefox to its default settings. d. Clear your browsing history and cookies.

  5. Google Chrome: a. Click on the three-dot menu and go to "More tools," then "Extensions." b. Remove any unwanted extensions. c. Reset Chrome settings to their original defaults. d. Clear your browsing data, including cached images and files.


Adware can be a persistent and potentially harmful annoyance, but by understanding how it operates, detecting its presence, and following the appropriate removal steps, you can keep your computer and personal information safe from its unwanted grasp. Stay vigilant, use reputable security software, and maintain healthy browsing habits to prevent future adware infestations.
