back to article Mozilla locks nosy Avast, AVG extensions out of Firefox store amid row over web privacy

The Firefox extensions built by Avast have been pulled from the open-source browser's online add-on store over privacy fears. Adblock Plus founder Wladimir Palant confirmed this week Mozilla has taken down the Avast Online Security and Avast-owned AVG Online Security extensions he reported to the browser maker, claiming the …

    "It is necessary for this service to collect the URL history to deliver its expected functionality."

    Why the history? I would have thought the current page would be enough. (Although if used for long enough they effectively have the history anyway.)

      You could argue that if you know the referrer and it's a cess pit of links to dodgy sites, then that's a fairly good reason for blocking the referring page too, I suppose.

      That said, I'd trust anyone making that statement as far as I can throw an overweight elephant.

      There's still a free version. It's filled with nagware about leaking IP addresses, discounts on the paid version, and "the Government can see what you do online" scare tactics.

      Re: Gosh, I remember when Avast was free

      I dropped it when I got spooked by Avast secretly inserting a proxy-SSL service in front of my 'NNTP' client, then finding out that it pretty much did that for everything SSL. Only NNTP was rarely used so little tested and this threw some exceptions.

      First thought was: "Why the f*ck would they do that!?" to scan for viruses obviously, but, what else could they do with that proxy?

      Then I figured that Avast was perhaps much *too* nice, polished and even well-maintained for a free piece of proprietary software. 'Someone' was maybe paying big money for the capability of building hashes of all the files on all computers on the planet and, for example, monitoring which hashes moves over SSL to where and likely having access to getting copies of the traffic going over SSL.

      'Someone' rolling in that kind of unquestioned, permanent, funding would be someone with interest in the communication gathering. Like the NSA or just maybe the CIA.

Analyze it however you want: track what users searched for, how they interacted with a particular brand or product, and what they bought.

      You are part of the problem, and whilst people continue to think like you.. nothing will change and people like me will continue to do everything in our power to block and render any data collected as worthless as is possible.

        well , you clearly feel very strongly about this but you've not actually mentioned what the problem is - just that you are opposed to data collection.

        Is it that the adverts you receive might be relevant to your interests? oh no ! the horror!

        So much amazing stuff is free on the internet because of things like this:

        - free email accounts

        - free antivirus

        - free adbnlockers

        - free ffs sake i dont need to draw u a picture

        Think of it like TV

        nobody like or wants adverts - but they make it free.

        And as i said , id rather give data away than money.

        I can even give my data away more than once to different parties

        i can copy and reproduce my data to give it away again.

        i cant do that with money

          "nobody like or wants adverts - but they make it free."

          Nearly correct but the adverts are paid for by you whether you watch them or not. Those hundreds of thousands of pounds for 30 seconds during the FA Cup final don't come from nowhere.

            you mean whenever i buy something some of that money is going to the marketing department of that company?

        2. Unicornpiss

          I wouldn't mind paying a reasonable fee..

 not be bombarded with ads. I'm far from rich, but we don't all have to accept the lowest common denominator just because it's free, do we?

          Mostly I will go out of my way to block every ad I can though. I don't mind the quiet, relevant ads such as on this site. I mean the blinking, aggravating atrocities that block content you're trying to view. And I hate the way you go to a site looking for software only to find 10 giant buttons to download worthless crap while the actual link to what you're looking for is about 1mm in size. Also hate when you're on a mobile device and navigating a minefield just to get to the next page of your article without inadvertently clicking on the trash that surrounds what you're trying to read. News sites that do that or that won't display content without turning off an ad blocker either get their ad scripts blocked by me or if too inconvenient, I can just find content elsewhere. The companies that allow these ads for a little revenue boost are scamming the system too--they only care that the ad shows as delivered, even if you instantly closed the popup before it finished loading, so they purposely make it easy to inadvertently click something you don't want. Which is just shitty.

          I make a point of utterly avoiding anything aggressively marketed in these ways, even when the product would be useful to me. And I think everyone should. People's acceptance of continual annoyances is why the Internet is a swamp that must be waded through to get to the clear water. Avoiding marketing and the capture of personal data is also one of the reasons that I use Linux everywhere I can.

        4. Teiwaz

          Think of it like TV

          I might agree (sort of) - I think a lot of users are more than happy with 'Free' in exchange for ads and usage tracking, they don't see the value on what they using to pay for these services, and won't until they get hit by an identity thief or some other fraud.

          Perhaps companies feel their product would be less attractive if consumers knew how much of their activity was monitored - most people will click through without reading impatiently anyway.

          But TV? It's not usually that free down to just ads, there's channels and who charge subscription and serve ads.

          And the rub is, even with all this data collection, companies who pride themselves on targeted advertising still seem to be wide of the mark - The fact that these companies think their 'expertise' might be useful in medical diagnosis scares me.

              If you're using a cable box or streaming service, who knows what telemetry is going back to the mothership. At least with a stream on a PC, if you have the ability, the time, and enough headache medicine, you can figure out some of what is being monitored. With a sealed cable box, with its own modem built in, who knows how much of your activity is being tracked? They may even know how long it took you to get fed up and mute a commercial, or change to another channel. And if you're using any kind of cloud-based DVR or one included by your service provider, all kinds of demographic info is being harvested. And you're paying a hefty fee for the privilege of having your activities monitored.

    If data has to be analysed maybe firefox can setup a cloud so the data is never actually received by the app makers.

    Ah yes, Avast

    My siblings laptop had been infected by a fake Firefox update that used PowerShell and Wscript to modify the Windows registry for persistence and to commit ad click-fraud pulling down hundreds of video ad impressions which I later recovered from the raw disk image I created using open-source recovery software .

    I had reached out to abuse department of the registrar only to be ignored even after escalting to a supervisor on a recorded call.

    Months later this registrar is mentioned only by their location in a semi-redacted endictment of a man extradited from the Ukraine.

    All the while a paid version of Avast was running quietly with nothing to report, partially knackered by a simple one-line script using the Windows TaskKill command.

    There is also a dodgy "antivirus/cleaner" app on the Play store that uses Avast's detection engine that can break out of it's sandbox to access other apps data by becoming a Device Administrator that many users have reported being tricked into installing by scary pop-up warnings that threaten users with SIM card damage or worse unless this app is installed only to get charged a fee if they do not unsubscribe within 3 days after install.

    This ad fraud can be traced as far back as 2013.

    From the Play Store reviews from December 2nd 2019:

    "Your scareware app has frozen my internet, threatened to lock my phone within 24 hrs if I don't download your app, use it for 3 days free then be given the privilege of paying $24.99 for a year of using it, charged to my cc on file with Samsung.

    If I'm charged I will sue you..."

    And then there are the many user complaints on Avast's user forums of Avast getting installed as a "bundle" when trying to install CC-cleaner, ignoring opt-out checkboxes and users reporting strange processes running on their Windows box with bizarre devil-may-care attitude response from the devs.

    I guess in a way I should be thanking Avast, it was the afore mentioned Android app that alerted me to what had been going on with Facebook years before it became a worldwide scandal and the reason I no longer allow ANY third party apps on my devices and the reason I learned how to flash my devices with Lineage OS and deleted all social media.

    The average person installs these "security" products to try and protect themselves from the very things these apps and browser extensions are doing.

    "Google Chrome is where the overwhelming majority of these users are..."

    Hardly worth using (or indeed blocking) these extensions if you're using Chrome. It does all the snooping you could want entirely unaided, as does Google by multiple other means.

    1. JCitizen

      Re: "Google Chrome is where the overwhelming majority of these users are..."

      @MIke 137 ----- That is exactly right. I install DuckDuckGo and it does a much better job blocking everything on the web sites than Avast did, and you can adjust the controls for each site and support sites that need the ad dollar to stay in business. It especially works on Chrome which is why it was developed. I'd swear Chrome runs faster with it enabled.

      Avast is fairly good for a free ware AV, but I have a life time license for MBAM, so I don't need it anymore. I use my PC as a restricted user, so the bugs can't take over, and simply run CCleaner to make sure no attack files are left over from surfing the web. Unfortunately Avast bought CCleaner, so now it is getting slow - but I don't know any other file cleaner that can remove Zombie files and LSOs, and the minute I can find one that is less of a problem,, I will switch to it.

    The makers of Avast became dodgy bloatware creators. I kicked Avast's ass to the curb years ago. Their software was slowing down PCs and even created some unexpected reboots and lost Windows system files during its time protecting against malware (but not protecting against itself). The very thing that was supposed to keep our computers safer became the very problem we desired to avoid.

    Best practices have kept our systems malware-free. Avast was purely a drain. Not surprised that they were slurping more data than was truly necessary through browser plugins, and kudos to Firefox for removing them from the addon store. This should extend to existing installs by way of an election page explaining things to the user, and giving them the option to remove the offending addons.

    1. JCitizen

      Avast used to be a good AV, but I found that a fully updated PC with all apps updated, and running as a restricted user, can protect against malware incursions just as well. However I still use the paid version of MBAM just in case, and it does well enough alone. I now recommend just using Windows Defender for most folks and train them to watch out and think before clicking on pop ups; and all is well - expecially if they clean the files often. Unfortunately Avast bought Piriform so now CCleaner is slowing down, but until I can find another free file cleaner that removes LSOs and Zombie files, I'll have to put up with another Avast product again.
