Your browser has been acting like it has a mind of its own. Ads everywhere. Your homepage changed to something you’ve never heard of. Search results going to weird sites that are definitely not Google. Sound familiar?
Good news: this is one of the most common and most fixable types of malware. Browser-based adware and hijackers are annoying, but in most cases you can clear them out in under ten minutes without any special tools.
Here’s exactly how to do it, on every major platform.
STEP BY STEP
Remove suspicious browser extensions
This is where most browser infections live. Extensions sit inside your browser and run quietly in the background – which makes them a favourite hiding spot for adware.
To find them, open your browser’s extension manager. Here’s where it is in each browser:
Once you’re in, look for anything you don’t recognise or didn’t install yourself. If you’re unsure about something, search the name online before removing it. When in doubt, remove it – you can always reinstall a legitimate extension in seconds.
Reset your browser settings
Most browsers let you restore default settings without deleting your bookmarks or saved passwords. This clears out hijacked homepages, changed search engines, and modified startup pages in one go.
This single step fixes a surprising number of browser problems. If your search engine and homepage are back to normal, you’re most of the way there.
Clear cookies, cache, and browsing data
Some adware uses stored cookies to re-hijack your browser even after you’ve removed the extension. Clear everything to cut that off.
Go to your browser’s history or privacy settings and clear:
Set the time range to “All time” – not just the last hour or day.
Revoke notification permissions
This one gets overlooked but it’s important. Adware loves browser notifications – those little pop-ups that appear in the corner of your screen even when you’re not browsing. Check which sites have permission and remove anything unfamiliar.
If you see a long list of random sites you don’t recognise, revoke all of them. Legitimate sites will just ask again when you visit.
Check for unwanted programs (Windows and Mac)
If the browser steps above didn’t fully clear things up, the infection might have installed something on your system as well.
Check for malicious profiles (iPhone and Android)
On mobile devices, some adware installs configuration profiles that change system settings beyond just the browser. These need to be removed separately.
Check app permissions (Android and iPhone)
While you’re in settings, do a quick permissions review. Go to Settings > Apps, tap each suspicious app, and check what it has access to.
These are all red flags. If an app’s permissions don’t match what it actually does, uninstall it.
Restart and confirm it’s gone
Restart your browser, or your device if you cleared profiles. Browse normally for a few minutes. If the redirects, pop-ups, and hijacked search results are gone and stay gone, you’re done.
If they come back after a restart, the infection is deeper than the browser. Check our step-by-step removal guide for:
IF IT KEEPS COMING BACK
If you keep getting reinfected
If adware keeps coming back even after you’ve cleaned it, it’s usually one of three things:
You’re downloading software from risky sources. Free software bundles are one of the most common ways adware gets installed. Always choose “Custom” or “Advanced” during installation so you can see what else is being added, and uncheck anything you didn’t ask for.
Someone else on the network is infected. If you share a network with other devices, malware can spread. Make sure other devices are clean too.
Your connection is being used to redirect you. On unsecured public Wi-Fi, attackers can intercept your traffic and redirect you to malicious sites without anything being installed on your device. You think you’re visiting a legitimate page – but you’ve been quietly sent somewhere else. A VPN like ZoogVPN encrypts your connection so this kind of attack doesn’t work. Your traffic becomes unreadable to anyone watching the network, which means no redirects, no interception, and no silent installs from sites you never meant to visit. It’s one of those simple habits that quietly prevents a lot of problems – worth turning on whenever you’re on a network you don’t control.
STAY PROTECTED WITH ZOOGVPN
Clean your browser. Then protect your connection.
Removing adware deals with what’s already on your device. But getting reinfected is often about what happens on the network before anything reaches your device at all.
ZoogVPN encrypts your internet connection so attackers on public Wi-Fi can’t intercept your traffic, redirect you to fake sites, or inject anything into pages you visit. It works on Windows, Mac, iPhone, and Android – one subscription, up to 10 devices.
Think of the steps above as cleaning up a mess. Think of ZoogVPN as not making the mess in the first place.
