The Best Ad-blocker Software in 2025

Total AdBlock is a leading adblocking solution in the market. It effectively removes all types of online advertisements, including banners, pop-ups, and even YouTube ads. This ad-blocker works as an extension for all popular web browsers. So, regardless if you're a Chrome, Microsoft Edge, Safari, Firefox, or Opera user, Total Adblock will help you regain control over your surfing experience – making it faster, safer, and hustle-free.

Great privacy tool

Not only does Total Adblock block annoying ads across the web, but it's also a powerful tool against tracking and third-party cookies. That means advertisers get far less opportunity to snoop on your activities and collect your data, which significantly reduces the chances of your sensitive information getting abused, and improves your overall privacy online.

Created by an award-winning antivirus provider TotalAV, and praised for its Savapi anti-malware engine, Total Adblock Premium is much more than just an ad-blocker. What's more, if you opt for Premium, you get its superb anti-malware and anti-virus protection for free – a valuable package worth trying out, especially since there's a 30-day money-back guarantee included in the offer.

Feature-loaded

Total Adblock is very lightweight by design, however, it's loaded with useful features. It offers an unlimited ad and tracking blocking service, plus it allows you to whitelist as many websites as you want (those you find trustworthy or wish to support). You can toggle this feature, called Acceptable Ads, according to your preferences and as many times as you want, which is very convenient should you change your mind about a website. It also allows you to experience a truly personalized ad-blocking service.

Quiet Mode is available too, thanks to which, you can disable pesky push notifications and manage your browsing history (clear cookies, cache, and similar). These features are not only super useful privacy and security-wise, but they also help you achieve much shorter page loading times (some sites that I tested loaded over 50% faster with Total Adblock on). Not to mention that they make your life much easier.

All-round service

If you're looking for a well-rounded service that includes all the above, plus an excellent customer support team that can guide you through the entire installation process and is available 24/7, Total Adblock could be just the right choice for you. If you are more of a DIY type, an extensive knowledge base comprising tutorials (How to install Total Adblock on Android, iOS, etc.), guides, and a list of FAQs is available on Total Adblock's official website too.

So, even if you are a complete newbie, it is most likely you won't face any difficulties setting up and using this ad-blocker. And, even if you do, you can always contact customer support, which, in my experience, is usually super quick and efficient. 

Surfshark’s CleanWeb is an ad-blocker and cookie pop-up blocker, as well as an alert service for malware and site-specific historical data breaches.

It’s available as part of every Surfshark subscription – through either the VPN app or browser extension. The latter has more functionality than the former, which only enables users to toggle the service on and off.

Opening the CleanWeb 2.0 browser extension takes you straight to the dashboard, which is as clean and intuitive as other Surfshark products.

If you land on a website that doesn’t work with CleanWeb, you can add its URL to a bypass list by clicking the plus symbol in the upper-right corner of the screen. Here you can also specify if you want the site to also bypass the VPN.

The CleanWeb 2.0 browser extension consists of four tools: the ad-blocker, pop-up blocker, data breach notifier, and the malware notifier.

The ad-blocker removes a host of adverts – including the video ads most commonly served by streaming providers. The pop-up blocker, meanwhile, prevents cookie requests. It acts in the background, rejecting any that are possible to reject and only accepting those that are strictly necessary for the chosen website to work.

The third feature – the data breach alert – notifies you if the site you’re on has ever been involved in a data breach. If it has, CleanWeb tells you when it happened and how many accounts were exposed. The malware detector tells you if any viruses or malware have been detected.

In the browser extension, you can choose which of these features you want to enable via the CleanWeb settings tab. Note that it isn’t necessary to be connected to the VPN for CleanWeb to function.

The CleanWeb 2.0 browser extension is available for Chrome, Firefox, and Edge browsers. As part of the Surfshark app, CleanWeb is available on iOS, macOS, Android, Windows, Linux, and Amazon FireTV.

AdLock is one of the best ad-blockers currently on the market in terms of functionality and advertising/tracking blocking and analytics. While there's no free tier, it offers a variety of reasonably priced subscription options, allowing you to pay month-by-month, for one year, or for five years.

It’s a little more intensive on resources than browser-based alternatives for mobile, but as a separate application, it can prevent auto-playing videos, pop-ups, and general advertisements mobile-wide and offers detailed stats to allow users to delve into what ads, trackers, and suspicious activities are being blocked.

In-depth information

If you've ever wanted to see exactly who and what is trying to serve you ads and trackers as you browse the internet, then AdLock is a great choice. From basic statistics showing you which URLs are being blocked, to reports on suspicious requests, intrusion attempts, and more, AdLock allows you near total control of what is, and isn't, allowed on your machine.

The only minor complaint here is that these features might be a little intimidating to new users, but you don't actually need to use any of them. Just turn AdLock on, make sure to hit that "Check for updates" button every now and again, and it'll just get on with things in the background.

Massive customization

AdLock offers protection on a per-app basis, allowing you to add and remove browsers and other programs as well as choose whether you wish to apply filters. You can even block an app entirely from the internet if you think it's being used just to serve you adverts. Where AdLock truly shines is that you can use it to block ads in all manner of apps, not just web browsers. Candy Crush showing you too many ads? Block them. Being forced to watch 20 seconds of adverts for a 2-minute-long YouTube video? Not anymore. Simply add the app into AdLock and kiss goodbye to adverts.

Responsive support

You can reach out to AdLock support through the browser or directly through the app. This is how you engage their support team if you find any sites that AdLock does not work with. We reached out to their support service when we found two sites that didn't work during our testing and in less than 90 minutes, they'd released an updated filter list that enabled both sites to work flawlessly. If this is the level of support all AdLock users can expect, then we are genuinely impressed and we think you will be too if you try it out risk-free with its 30-day money-back guarantee.

AdGuard is another great stand-alone ad-blocker, available for all popular devices, including Android, iOS, PC, and Mac. Same as AdLock, this service offers more than just a browser extension. It works with many apps that would usually pester you with adverts, including YouTube and Twitch. You get to enjoy faster and smoother browsing and streaming without interruptions, and save on bandwidth and system resources that are typically wasted on ads and cookies activities.

Highly customizable

AdGuard comes with many useful features and impressive customization. You can set up and customize different filters for all kinds of ads and trackers, individually, or all at once. Ad-blocking filter categories are already listed and well-organized, which helps to speed up the customization process, including super useful social media-related filters (we all know how annoying these can be).

What's more, AdGuard filters code from sites before they even load. This stops ads before they begin their download, saving a substantial amount of your time and system resources.

Guarding your privacy

Another great AdGuard feature is Stealth mode, which comes with an array of options for blocking. This mode stops ads and trackers, but also a range of other files and components that could compromise your security. With AdGuard, you have options to hide your search queries (so websites can't keep track of them), protect your IP address, block or limit cookies, and many others. All these can make a tremendous difference in protecting your privacy and keeping you safe online.

Protects all your browsers, apps, and devices

One of the best things about AdGuard is that it comes in different shapes and forms, so it can suit all your needs on a day-to-day basis. And so, you can choose between a stand-alone desktop version available for your macOS and Windows devices or a browser extension that works across all popular browsers, including Google and Safari.

You can download and use any basic AdGuard protection (on an individual device) for free. However, should you wish to try upgraded versions, two of them are available for purchase. They offer additional functionality and can be used on up to nine devices. Besides, a paid version comes with a generous 60-day money-back guarantee – which means you can try it risking no cash.

uBlock Origin (uBO) is a popular free and Open-source cross-platform ad-blocker that also has some quite effective anti-tracking capabilities. uBlock Origin is a fork of the original uBlock, so don't get the two mixed up! The original uBlock is now part of Adblock Plus and takes part in the whitelisting of some adverts, so if you're looking to block as many as you can, then make sure you get uBlock Origin.

Feature heavy

uBlock Origin is an unobtrusive, lightweight offering compared to some competitors, but that doesn't mean it's bringing a wiffle bat to a knife fight. It's got custom blocklists, dynamic filtering, element inspector, and zapper so you can block specific parts of a website, site-specific pop-up blocking, and even the ability to whitelist sites that you want to support directly or where the adverts aren't too intrusive.

Block pre-fetched links

These days, most browsers try to speed up the browsing experience by preloading the other links on a page while you are busy reading that page, whether you have any intention of clicking on them or not. Not only does this waste bandwidth unnecessarily, but if you are not using a VPN to hide your IP address from these pre-fetched pages, it further exposes your personal details to these sites without you ever visiting them. Fortunately, this is an issue that uBlock Origin can fix.

Malware protection

Besides advertising block lists, uBlock Origin also uses lists of known malware distributors to automatically block those for you as well! All of uBlock's block lists are further maintained by a community of volunteers, no compromises are made to whitelist certain sites, and no worries that it might be doing something nefarious with your data.

NordVPN's CyberSec option isn't free like some of the other options on this list, as part of a NordVPN subscription, but it's still a compelling offering, especially when bundled with an industry-leading VPN to further secure your connection and online privacy. While it lacks in-depth customization options, literally being either ON or OFF, it still offers a good level of protection against all kinds of malware.

Foolproof functionality

While perhaps lacking the functionality that power users will crave, NordVPN's CyberSec is a great way for novice users to further secure their internet connection. With no configuration needed, users can simply turn it on and leave it running in the background, confident that NordVPN has their backs and will be actively protecting them from malicious sites, ransomware, and more.

Blocking malicious websites

CyberSec, and other security products, use filter lists of dangerous/suspicious websites to identify potential threats as you browse the internet. It scans any address you enter against these lists and if it finds a match will block access to that site before you can connect to it. In this way, it ensures you cannot accidentally browse to any sites known to host malware.

A little too simple

Really, the only reason not to recommend this product is that it's all-or-nothing, on or off, there's no way to customize it, no way to set up your own filters to avoid specific sites, or even to work around potential false flags which do happen from time to time. That said, it's a useful tool if you already have a NordVPN subscription and a great way for the non-technical user to further secure themselves online.

While AdFender no longer offers a free option as of version 2.50, but it remains one of the best ad blockers for Windows PC users, offering official support right up to Windows 10. It's one of the cheaper paid ad-blockers out there, available for as little as $15.95 per year. It has been tried and tested using a wide range of browsers, including Waterfox and Pale Moon, two of the more privacy-focused browser offerings out there.

HTTPS filtering

Similar to AdLock, AdFender works by running as a proxy server on your PC to filter out potentially dangerous content. It filters all the web traffic from your machine, and if it detects that the URL that's trying to load is one that's used to serve adverts, it blocks it. It's even cable of filtering secure HTTPS connections and helping to anonymize your online presence by routing all your traffic through the Tor network, though this will hurt your connection speeds, as Tor is not known for being particularly fast.

Browsers and more

As with AdLock, AdFender is installed on the operating system rather than just as an extension in your browser, so it can protect more than just your web browsing. As well as sporting an impressive list of supported browsers that includes not only the big, well-known ones but all kinds of smaller, niche browsers as well including Yandex, Epic, and more.

It can also work with various instant messaging clients. It does all this without having a major impact on your system resources too.

Better browsing

AdFender helps not only speed up your browsing experience, webpages load faster when they don't need to waste time loading intrusive banner and video ads, but it saves you bandwidth as well. By automatically detecting and rejecting advertising URL requests, it protects people on metered connections from frittering away their precious download allowance on potentially malicious adverts.

1Blocker (formerly 1Blocker X) was one of the first ad-blockers for iOS devices such as iPads and iPhones, and remains a popular and effective choice for Apple users. While it is limited to only blocking adverts in the Safari browser, it does it very well and is still a useful tool for saving both system resources and bandwidth by preventing content from downloading in advance. It does have a free tier, but the paid version requires only a small onetime payment to unlock all its features and filtering options.

Better browsing

It would be unfair to call 1Blocker "just" an ad-blocker. It's capable of blocking not only unwanted ads, but all manner of social media trackers, all those widgets for sharing content on multiple platforms, and it can even block custom fonts which can be a help to those who have dyslexia. One of the most interesting options is the ability to block those oh-so-annoying "here's how we use cookies" banners that have been a pox on the internet since the introduction of the EU's ePrivacy Directive in 2018.

Tracker blocking

A recent update to 1Blocker has seen it expand its tracker-blocking functionality outside of just the browser. Sadly, there's still no system-level ad-blocking, but now you can block all those pesky social media trackers in other apps as well as just Safari. Building on 1Blocker's App Tracking Transparency, which forces apps to ask for permission before they track you, Firewall now just automatically blocks the trackers, adding another layer of privacy and security between you and companies eager to track everything you do online.

Fully customizable

Out of the box, 1Blocker is already a solid choice for an ad-blocker, but it builds on this foundation by providing the functionality to create custom rules. It will allow you to create your own custom filters to block any URL you like by using a regular expression or hide any element in CSS. However, this feature is only available to paid users, otherwise you're stuck with just the default filters, which are still nothing to sneeze at as these are kept regularly updated by 1Blocker.
