How To Remove Adware From Windows 10 : Uninstall Adware Programs Safely

by

Adware on Windows 10 often hides in browser extensions and startup programs that require separate removal steps. If you are seeing pop-ups, new tabs, or random ads even when no browser is open, your system likely has adware. This guide will show you exactly how to remove adware from Windows 10 using built-in tools and free methods.

Adware is not a virus, but it is still annoying and can slow down your computer. It usually sneaks in with free software downloads. The good news is that you can clean it yourself without paying for expensive software.

We will cover manual removal steps, using Windows Security, and checking browser settings. Follow each step in order for the best results.

How To Remove Adware From Windows 10

Start with the most common hiding spots. Adware often installs itself as a regular program or a browser add-on. You need to check both places.

Step 1: Uninstall Suspicious Programs

Go to your list of installed programs. Look for anything you do not remember installing. Adware names can be generic like “Web Helper” or “Toolbar.”

  1. Press the Windows key and type “Add or remove programs.”
  2. Click the result to open the list.
  3. Sort by “Install date” to see the most recent ones first.
  4. Look for programs with weird names, no publisher, or that you never installed.
  5. Click each suspicious program and select “Uninstall.”
  6. Follow the prompts. Some adware will try to trick you with “No thanks” or “Keep” buttons. Read carefully.

After uninstalling, restart your computer. This removes any running services tied to the adware.

Step 2: Remove Adware From Browser Extensions

Adware loves to live in your browser. It adds extensions that inject ads into every page you visit. Check each browser you use.

Google Chrome

  1. Open Chrome and click the three dots in the top right.
  2. Go to “Extensions” then “Manage extensions.”
  3. Look for extensions you did not install. Turn off the toggle and click “Remove.”
  4. Also check the “Details” button for any permissions that look wrong.

Microsoft Edge

  1. Click the three dots in the top right corner.
  2. Select “Extensions” from the menu.
  3. Find any unknown extensions and click “Manage.”
  4. Click “Remove” to delete them.

Mozilla Firefox

  1. Click the menu button (three lines) and choose “Add-ons and themes.”
  2. Go to “Extensions” on the left.
  3. Disable or remove any add-ons you do not trust.

After cleaning extensions, reset your browser settings. This removes any changes the adware made to your homepage or search engine.

Step 3: Reset Browser Settings

Adware often changes your default search engine and homepage. Resetting the browser fixes this without deleting your bookmarks.

Chrome Reset

  1. Go to Settings (three dots > Settings).
  2. Scroll down and click “Advanced.”
  3. Under “Reset and clean up,” click “Restore settings to their original defaults.”
  4. Confirm by clicking “Reset settings.”

Edge Reset

  1. Go to Settings (three dots > Settings).
  2. Click “Reset settings” on the left.
  3. Choose “Restore settings to their default values.”
  4. Click “Reset.”

Firefox Reset

  1. Go to Help > More troubleshooting information.
  2. Click “Refresh Firefox” in the top right.
  3. Confirm the action.

Using Windows Security To Scan For Adware

Windows 10 has a built-in antivirus that can find and remove adware. It is free and works well for most threats.

Step 4: Run A Full Scan

  1. Open the Start menu and type “Windows Security.”
  2. Click “Virus & threat protection.”
  3. Under “Current threats,” click “Scan options.”
  4. Select “Full scan” and click “Scan now.”
  5. Wait for the scan to finish. It can take an hour or more.
  6. If threats are found, click “Start actions” to remove them.

After the scan, restart your computer. This ensures any quarantined files are fully removed.

Step 5: Use Microsoft Defender Offline Scan

Some adware is hard to remove while Windows is running. An offline scan boots your computer into a safe environment and removes stubborn threats.

  1. Open Windows Security again.
  2. Click “Virus & threat protection.”
  3. Under “Current threats,” click “Scan options.”
  4. Select “Microsoft Defender Offline scan.”
  5. Click “Scan now.” Your computer will restart and begin scanning.
  6. After the scan, Windows will boot normally and show results.

Checking Startup Programs And Task Scheduler

Adware often sets itself to run every time you start your computer. Removing it from startup stops it from coming back.

Step 6: Disable Suspicious Startup Items

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. Click the “Startup” tab.
  3. Look for programs with “Unknown” publishers or weird names.
  4. Right-click any suspicious item and select “Disable.”
  5. Do not disable things like your antivirus or audio driver unless you are sure.

Step 7: Check Task Scheduler

Some adware uses scheduled tasks to reinstall itself after removal.

  1. Press the Windows key and type “Task Scheduler.”
  2. Open the app.
  3. Look through the list of tasks for anything with adware-like names.
  4. Right-click and select “Disable” or “Delete.”
  5. Be careful not to delete system tasks. If you are unsure, search the task name online first.

Cleaning Browser Data And Caches

Adware can leave behind scripts that reload even after removal. Clearing your browser data removes these leftovers.

Step 8: Clear Cache And Cookies

  1. In Chrome, go to Settings > Privacy and security > Clear browsing data.
  2. Select “All time” for the time range.
  3. Check “Cookies and other site data” and “Cached images and files.”
  4. Click “Clear data.”
  5. Repeat for Edge and Firefox if you use them.

After clearing data, close and reopen your browser. Check if ads are gone.

Using AdwCleaner For A Deep Clean

AdwCleaner is a free tool from Malwarebytes that specializes in adware. It finds things that Windows Security might miss.

Step 9: Download And Run AdwCleaner

  1. Go to the Malwarebytes website and download AdwCleaner.
  2. Run the installer. It is a small file.
  3. Click “Scan now” to start.
  4. After the scan, review the results. It will show adware, PUP (Potentially Unwanted Programs), and browser hijackers.
  5. Click “Quarantine” to remove everything.
  6. Restart your computer when prompted.

AdwCleaner also cleans browser settings and resets proxy settings that adware might have changed.

Checking Proxy And Network Settings

Some adware changes your proxy settings to redirect traffic through ad servers. Fixing this stops the ads.

Step 10: Reset Proxy Settings

  1. Press the Windows key and type “Proxy settings.”
  2. Open the result.
  3. Under “Manual proxy setup,” make sure “Use a proxy server” is turned off.
  4. Also check “Automatically detect settings” is turned on.
  5. Scroll down and click “Save.”

If you see a proxy address that you did not set, that is a sign of adware. Remove it and save the changes.

Preventing Adware In The Future

Once you clean your system, you want to keep it clean. Follow these tips to avoid reinfection.

  • Only download software from official websites. Avoid third-party download sites.
  • During installation, choose “Custom” or “Advanced” options. Uncheck any offers for toolbars or extra programs.
  • Do not click on pop-up ads that say your computer is infected. Those are often adware themselves.
  • Keep Windows and your browsers updated. Updates fix security holes.
  • Use an ad blocker like uBlock Origin. It stops many adware scripts from loading.
  • Run a quick scan with Windows Security once a week.

What To Do If Adware Keeps Coming Back

Sometimes adware is stubborn. If you have followed all steps and it returns, try these advanced methods.

Use System Restore

  1. Press the Windows key and type “Create a restore point.”
  2. Click “System Restore” and choose a date before the adware appeared.
  3. Follow the prompts to restore your system.

Create A New User Account

  1. Go to Settings > Accounts > Family & other users.
  2. Click “Add someone else to this PC.”
  3. Create a new account and log into it.
  4. If the ads are gone, move your files to the new account and delete the old one.

Reset Windows 10

This is the last resort. It removes all programs and settings but keeps your personal files.

  1. Go to Settings > Update & Security > Recovery.
  2. Under “Reset this PC,” click “Get started.”
  3. Choose “Keep my files.”
  4. Follow the instructions to reinstall Windows.
