Ads keep opening in new tabs? Stop browser hijackers

Yeah, I know that feeling. You're just browsing, and suddenly a tab pops up with ads for weight loss pills or weird browser games. It's annoying and makes you feel like your computer's broken. But it's not broken. It's just got some junk software on it. Let's clean that out.

First step: check your browser extensions

Most of the time, it's one bad extension causing this. Here's how to check in Chrome, Firefox, and Edge.

1. Open your browser. Click the three dots in the top-right corner (Chrome or Edge) or the three lines (Firefox).
2. Go to Extensions or Add-ons (in Firefox it's under Add-ons and themes).
3. Look at the list. Do you see anything you don't remember installing? Something like "Shopping Assistant," "Tab Manager," or "Safe Search"? Those are common names for adware.
4. Turn off each extension one by one. After turning one off, close your browser and open it again. See if the ads stop.
5. Once you find the bad one, click Remove (not just disable).

Expect this: After you remove it, your browser might ask you to confirm. Say yes. Then close and reopen the browser. The ads should be gone. If they're not, move to the next step.

Second step: reset your browser settings

Sometimes adware changes your browser settings without asking. You need to undo that.

For Chrome:

1. Click the three dots > Settings.
2. Scroll down and click Reset settings.
3. Click Restore settings to their original defaults.
4. Click Reset settings in the pop-up.
5. After you click it, Chrome will restart. You'll lose your pinned tabs and startup pages, but bookmarks and passwords stay.

For Firefox:

1. Click the three lines > Help > Troubleshooting Information.
2. Click Refresh Firefox.
3. Click Refresh Firefox again to confirm.
4. Firefox will close and reopen. It'll save your bookmarks and passwords.

For Edge:

1. Click the three dots > Settings.
2. Click Reset settings on the left.
3. Click Restore settings to their default values.
4. Click Reset.

After this, your browser should act clean. But sometimes the adware is deeper.

Third step: remove adware from Windows (the real fix)

If the problem keeps coming back, the malware is installed as a program on your computer. Here's how to find and kill it.

1. Open Control Panel. Type "Control Panel" in the Windows search bar (press the Windows key and start typing).
2. Click Uninstall a program (under Programs).
3. Sort the list by Installed On (click the column header). Look for anything installed around the time the ads started. Common names: "PriceGong," "Conduit," "SearchProtect," "Delta Search," "Search Manager."
4. Select the suspicious program and click Uninstall. Follow the prompts.

After each uninstall, restart your browser. Check if the ads are gone. If you see a program you're not sure about, Google its name plus "adware" before removing it.

Still having problems? Run a scan with Malwarebytes (free version works fine). Download it, install it, run a scan, and let it remove what it finds. I've used this on hundreds of machines and it catches stuff Windows Defender misses.

Why this works

Adware works by injecting code into your browser. It sits between the web page and your screen. When you click a link, the adware checks if it can redirect you to an ad. If yes, it opens that ad in a new tab. By removing the extension or the program, you cut the connection. Resetting the browser wipes out the settings the adware changed. That's why the fix works.

Less common variations

Sometimes it's not an extension or a program. Here are two rarer causes:

1. Push notifications from a website

Some websites ask "Allow notifications?" and people click yes by accident. Then the site sends ads as notifications. To fix this in Chrome: Settings > Privacy and security > Site Settings > Notifications. Look for sites on the "Allowed" list that you don't trust. Click the three dots next to them and choose Block.

2. A browser hijacker in the registry

This is rare but nasty. It adds a scheduled task that re-installs the adware after you remove it. Use Malwarebytes for this. Or use the free tool AdwCleaner (by Malwarebytes). Download it, run it, click Scan, then Clean. It's made exactly for this kind of problem.

Another trick: check the Startup folder. Open Task Manager (Ctrl+Shift+Esc), click Startup tab. Look for anything weird and disable it.

How to stop this from happening again

Here's the honest truth: most adware comes from free software you download. That free PDF converter, that video downloader, that driver updater. They bundle adware in the installer. You have to read every screen during installation and uncheck boxes that say "Install XX toolbar" or "Set your default search to XX."

Also, don't click "Allow notifications" on a website unless you know what it is. And don't click ads that say "Your computer is infected" or "Download now." Those are how the adware got in the first place.

Use uBlock Origin extension. It blocks ads and also blocks many adware domains. I've had it on my own browsers for years. No adware issues since.

And for extra safety, run Malwarebytes once a month. It'll catch things before they start the ad tabs.

One last thing: if you've done all these steps and your browser still opens ad tabs, it might be a problem with the browser itself. Uninstall the browser completely, restart your computer, then reinstall it fresh. That's the nuclear option, but it works when nothing else does.
