If figured out Avast is tracking and selling data to advertisers. I have uBlock Origin installed and I was randomly getting a popup warning about advertising tracking no matter what site I'm on. At first I didn't know what was causing it. When I disable the Avast extension this it warning stops.

along with total ad blocker and guardio, which i use along with avast, this extension is really nice in the realm of free security extensions! highly reccomend

Avast seems to be blocking my AD BLOCK and I have 4 Avast acounts and have been thinking about leaving them and start using Norton if this continues.

Where did tracking protection go? It's a shame that half of the features are behind a paywall. Might as well just make the extension a list of links you can visit to opt-out of popular advertisers.

DA H September 25th, 2022

the anti tracking feature is now behind a paywall rendering this extension pretty much useless

The anti-tracking feature is no longer free for Windows 11. Avast tells you to upgrade to Avast One.

Akotski1338 January 23rd, 2021

this extension used to show other people's rating of a website and it would allow me to know if a website ive never visited before is trustworthy. now all it does is block trackers. i dont know if someone bought avast or whatever but it recently became a piece of garbage

It looks like an advertisement for Avast One (which is good for a cellphone), and offers a free download. But, the download is for windows or mac and I'm on a chromebook so I can't use it. A couple of pop up ads came thru and that never happened before. It does let me know if I'm being tracked. If you block 3rd party cookies it won't let you opt out of some tracking. It let me block all but one.

Nice extension, works well. I've particularly enjoyed the (until recently) free anti-tracking feature! I am of course, writing this review since they now demand payment for this service. I have some sarcastic remarks I'd like to make, but for now I will hold my tongue and offer some help to any other users who recently noticed this. If you go find where Chrome stores extensions and determine which folder holds this one, it seems 22.3.143_0 was added today (May 31, 2022). If Chrome hasn't deleted the previous version, you may be able to reinstate it. Good luck! Now, I suppose I could just … not be a cheapskate, and buy Avast One Premium like it says to but... no. I find it funny they renamed the extension "Avast Online Security *and Privacy*" only to now remove the best (and quite a long-standing) privacy feature. I really want to rant about it, but this review is too long already.

This and avasts anti virus used to be good. But they're just getting more and more greedy. The anti virus is pretty much just adware now, and we cant even block trackers anymore with this extension

Nikita Kokoriev March 31st, 2022

Unfortunately, the checker generates false positive alerts, which can lower the user's trust rating for sites that do not have these problems. I think that such situations are unacceptable for a company of this level. Upd:The problem was quickly solved within a day.

蔡克文 March 3rd, 2022

Cloudflare is considered as a virus since today...what the hell? cannot access dashbaord

when I enable the Avast extension in my google chrome its shows a lot of errors in my chrome console. which do create a panic condition during development and debugging.

Keeps popping up 3rd party ad tracking notice when I expressedly opted out. Says toggling a switch will opt out of future ones but new ones are still added. And this is within 3rd day from switching that option. Can't trust an extension like this to secure browsing.

Tis deserves a ten-star review (if that was possible)! ⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐ I have never had a problem with it. I love the fact that, unlike other online privacy and security extensions, You do not need to pay for it. I have another extension, WOT, that has a maximum of only three rackers blocked if you don't have Premium. Moreover, they keep sending me emails encouraging me to buy their premium subscription. Another great feature of this extension is the guides/privacy advisors. They help me optimize my settings on websites to ensure my security and privacy. Last of all, the most beautiful thing about this extension is the pop-up that appears whenever I enter an unsafe site, along with the badge next to sites in the search page. (Also, I have downloaded the antivirus app, and it is amazing!)

Dominik Adrian Grzywak November 11th, 2021

With the ability to vote on the website being removed, the extension became less useful. There's a lot of malicious websites Avast marks as OK, and there's no possibility to report it through the extension.

It work really cleanly and it always gave me the option to block the viruses and always told me how many were blocked or not. Thanks for the great addon and it will always be good

I loved this software but since the update it says everything is safe so if I click on the website I get a virus thinking the website is safe.

Allen of Black Steel October 27th, 2021
Allen of Black Steel

The latest version I can't get used to it. man I missed my previous version. previous version I know that green icon means safe, fainted color means unkown, orange means this website is not trusted, red means dangers. but news version I see oranges and I have no idea what is going on.

Bill Naylor October 26th, 2021

I love Avast in general and this extension in particular. If you use Avast Antivirus on your PC, there's a Boot Time scan that checks your drives before Windows starts - gets at rootkits and registry issues. Really, really good. I've been using it for years. Even my elderly dad doesn't get viruses. Anybody using McAfee is a target.....Avast takes good care of you.....

Andrew Milo September 30th, 2021

it's wiping the settings from a crypto website i use for trading, causing the extension i've paid for to keep getting unregistered. I added the website to the exceptions list in the application, and also changed the extension settings so a click is required for avast to access the website. An hour later an avast sidebar appears while i'm using the website asking if I trust the website, plus some other boxes that appeared greyed out. I click the thumbs up, then i noticed the extension had automatically reactivated. When i changed the settings required a click to enable, Avast's memory usage dropped from 640mb to 177mb. I will be looking at different antivirus software soon, this one is too intrusive.

Kris Kurnia September 29th, 2021

I've been using this extension for years, and never had a problem. I'm using Avast antivirus for my PC for about 16 years and since using Avast, my computer has never had a virus. Please make this extension compatible with brave browser too. For other users, please remember, this extension is the first layer of protection, but you need an antivirus installed on your PC as the second layer and the strongest protection. And if there is a warning of a dangerous site, do not continue to visit that site.

Before you think I'm a paid reviewer nor an employee. I have been Avast since 2011 and I have to say as a former Norton and McAfee user Avast has never failed me and neither has this extension. I've had this extension for over 6 years and has not yet failed me and I hope it never does so, who ever is the developer of this extension keep up the good work and please don't make me look bad.

Nadege September 19th, 2021

I've been using Avast for years now, and even with the free version I've been able to get my PC fixed from any kind of virus attack. I now use the premium version and have not had one single virus for the years I've been using it. Also, it uses much less resources than any antivirus I've had in the past. Thanks for being there!

Perhaps this is a good extension, but I didn't ask for it to install, and it's persisted for over 2 years. This extension automatically installs itself, along with Avast SafePrice, every single time I install Chrome (or any other Chromium-based browser). I never installed either of them, and I can't find the source. They're not attached to any of my Google accounts and, after uninstalling them, I can find no trace of them inside my computer. Yet, launch a new Chrome profile (even after an uninstallation and re-installation), and there they are again, both Avast extensions installed, fresh as a daisy! Neither Google nor Avast have been able to understand the issue, let alone help me with this.

This company Avast is shady, it gives bad reviews of other search engines but gives great reviews of it's own search engine ( through it's search extension, which it forced on me during the install. It is very anti competitive. AVG (, and Zone Alarm ( did the same thing. They give other search engines false bad reviews through their products to help get users to use their shady products. If a business does shady business like that can you really trust them to protect you? Not at all. Shame on Google for not removing them from the Google store.

so many here complaining about connectivity that makes me wonder how much spyware is actually being blocked by Avast to slow it down :) clean your system boys so you antivirus dont have to block most of your traffic. And also that is a perfect example of clueless instaling best antivirus Avast, so than to disable it as like continue trojans use in illegal sources programs from "free" sites :D


That is good extension i give 5 starts.

Extension is great. Note to others who are having problems... you need to have a premium subscription for it to work properly. Otherwise its not really an extension, lol. Highly recomended.

This Extension is Great it protects you from suspicious Websites and Malware also it detects tracking system on a website which makes it Great Extension for online Security it also Op out from ads based on your personal interests I really Recommend Downloading this extension on your browser but that bad thing about this extension that it don't give that much of details about a specific website I hope they update it as soon as possible !?

Avast works very well to help me maintain performance on my computer and scan for viruses. However, Avast does not respect its users' privacy the way one might hope (or might have been expecting). This is why my rating is not higher. For more information, see the article by Joseph Cox, "Leaked Documents Expose the Secretive Market for Your Web Browsing Data" (An Avast antivirus subsidiary sells 'Every search. Every click. Every buy. On every site.' Its clients have included Home Depot, Google, Microsoft, Pepsi, and McKinsey.) VICE (January 27, 2020)
