Norton antivirus's inbuilt cryptominer has re-entered the public consciousness after a random Twitter bod expressed annoyance at how difficult it is to uninstall. The addition of Ncrypt.exe, Norton 360's signed cryptocurrency-mining binary, to installations of Norton antivirus isn't new – but it seems to have taken the non- …

    What does installing a crypto miner have to do with computer security?

    So taking 100% of the profits from surreptitiously installing a bitcoin miner is bad, but taking 15% is not bad?

    There's no point in them saying 'but it's opt-in' or 'but we tell you during install'. They know full well that it's going to be ignored. And because it's not a normal part of any security suite, who would expect it to be there anyway? I know I wouldn't. It's disingenuous and they know it.

    Typical of that poisoned brand anyway. For the last 18 years or so, it's been a scam. I remember I bought Norton 2003 for resale to customers and it was just about OK. After that, it got to be the resource hog and scam-monster it is today.

      It's been a long time since I ran into a PC with Norton on it. But was/is Norton the one you have to sign into your online account to find out if your antivirus is about to expire?

      I really found that annoying when I'm fixing a PC and can't tell the user they need to upgrade their antivirus soon. I never recommended Norton because of that.

      Never mind the computing resources it uses – the literal power is a potential real-world problem. Having been playing RDR2 quite a lot over the "festive" season* I was actually able to see the difference in my electricity bill resulting from the additional ~120W used by my graphics card running at full tilt rather than just ticking over (it also kept my feet warm). If you're paying the electricity bill, mining on non-specialist hardware in the UK is probably a net cost at the moment.

    Classic gift card balance "exploit"

    From the GSD entry GSD-2022-1000002 (

    Norton AntiVirus now includes an Ethereum crypto miner that has several problems including deceptive rewards program and difficulty in uninstalling it.

    Norton keeps 15% of all Ethereum mining proceeds and "pays" the remainder into a users "Norton Crypto Wallet" which is hosted by Norton. It should be noted that the Norton Crypto Wallet cannot be used to make Ethereum transactions, but can only be used to transfer value to a Coinbase account once a certain minimum threshold of value is accrued. The Norton crypto mining and Norton Crypto Wallet are effectively a gift card system where the money can be withdrawn, but not unless a certain balance is available. It should also be noted that the Norton Crypto mining software is reportedly very difficult to uninstall, requiring administrative level privileges, and even then reports indicate effective removal is difficult.

      I sympathise, I once manned a stand at a trade show and found myself unable to play the video files I had been supplied with. This was because some idiot had done them as an incompatible format for the flat screen tv we had. I spent the last of the set up/construction days converting the files on the worlds slowest phone (mine) because the laptops hadn't arrived by that point. MD turned up midway through the day and asked what I was up to. I explained and he sighed got his phone out, dialled a number and said to whoever answered it "We employ idiots in your department" then hung up.

      He had apparently called the Marketing Director and berated him. The marketing team had been the ones who supplied the videos. Despite them having been told the model of the TV and the formats supported they'd ignored it. MD then called to find out where the laptops were. He liked my ingenuity in using my phone to convert the files in the absence of anything else. Then he went off for a good lunch at the nearest decent pub and left me to my own devices and my own lunch.

        I did a show in London once where as our local VP arrived to do his tour of the very expensive booth, I was up a stepladder gaffer-taping CAT5 cables to the booth structure. The reason why, I had to explain to him, was that the numpties who’d built the booth had laid out all the cabling on the ground, to every location where it’d be needed. And had then built the entire booth right on top of the cables. Crushing every single one. When we were allowed onto the booth, scant hours before go-live, I wasted precious time terminating, testing, rejecting, re-terminating, etc etc, before realizing the root cause.

        Didn’t allow myself to get too cross with the stand builders though. Never argue with a man who has a nail-gun, claw-hammer, and knuckle tattoos. Oh, and who is busy rolling up acres of temporary carpet for disposal…

    "Norton 360's... cryptominer... is tricky to delete"

    When I was on tech support, removing Norton in any part or form was 'tricky' at the best of times.

    In many cases, it was necessary to download a specific removal tool from Norton directly to get it off (and there were several variants even of that). And things got a whole lot worse if someone had activated that ridiculous system Norton had at one time which took over the boot process. That thing was quite capable of bricking someone's machine if it went titsup (and it quite often did).

    When that happened, the only way of helping people was to send them the necessary boot disk (also from Norton) that alleged to put things right and remove it completely. Back then (early noughties) people tended to have one computer so only the one means of accessing the internet to download anything.

    As an aside, I get a giggle when I clear out my spam folder periodically and scan down the list of subject headers: 'LAST WARNING: Your Norton Subscription is About to Expire' or 'Your Norton Subscription Has Expired'. Also McAfee.

    Yeah, right. Like I have ever had any Norton installation files on any machine I've owned.

            The Ghost partition or whole disk erase could be booted off a W98 floppy. Very useful to wipe disks before returning kit to IT support - who tended just to reprime the disk for another user.

            Still use it occasionally with a USB floppy or bootable CD - as long as the BIOS disk controller can be set to "IDE". Use BCWIPE and ERASER too - but they tend to be restricted to use on a dedicated PC.

    There has been malware that installs bots on computers for a long time. Anti-malware programs like Norton try to block them, often with success. In this case Norton is installing a bot that works for Norton. Yes, the owner of the Norton license gets most of the money, but that does not change the fact that Norton is using its customers' computers to make money via crypto mining. This is a clear conflict of interest. At the very least, the opt-in policy should be much more explicit, and the executable should not even be downloaded unless the user explicitly agrees.

    The is one of the reasons I use Windows Security instead of a third-party anti-malware program. Microsoft's motivation is to protect the reputation of Windows, and that's it. The third-party tools are scrambling to make a dollar and will occasionally do this sort of drive-by install.

The program contains technology developed and protected by various means (copyright, trademark, patents). you may not disassemble or peek under the hood (except where allowed by law) .

    1. Boothy

      Re: Opt-in, my arse

      Bit like some recent TVs that pop us several EULA windows on first boot, for you to accept before you can use the TV.

      But one of the EULA is for advertising, but you have to read through it to figure that out, and if accepted, it enables adverts in the EPG.

      You can choose to decline that specific EULA, but how often is that ever an option? So most people assume you need to accept to continue, without realising you can actually decline and not get the adverts!

      To me, these type of questions should be explicitly asked, not hidden in a block of text in the EULA.

      i.e. something like:

      Step 1: Do you want to enable adverts? Yes/No (or Crypto etc).

      Step 2a: If No selected, don't enable and move to Step 3.

      Step 2b: If Yes, show the advertising EULA, and allow acceptance or rejection.

      Step 2c: If Accepted, enable adverts, go to step 3.

      Step 2b: If rejected, do not enable adverts, go to step 3.

    Heh Norton

    Over the last few years I've found it installed on enough PCs and laptops to know plenty of people still use it. Without the crypto stuff enabled, it isn't any worse a drag on resources than any other consumer AV software - if you're not still using something you built in the early 90s.

    And in terms of performance/protection, pretty much all mainstream, commercial AV suites are more or less equal - which is to say slightly better than having Windows Defender but a long way short of having real endpoint s/w and h/w protection.

    What I find funny though is how people are proudly stating they ditched products like Norton in comment entered using Google Chrome or Firefox.

    You don't get to be superior about not installing software that makes free use of your PC when you gift tech companies all your personal information. And if you use any social media or have installed a smart device? ROFL at the people that do this and then claim they know what they're doing because they avoid McAfee or Norton.

    GDPR customer opt-out. Would this be allowed?

    Could a publisher as part of the subscription agreement insert an opt-out clause for GDPR for meta data and actual data, as well as the subscription itself? The customer could explicitly opt out, which would raise a defense in the event of an enforcement action.

    There could be two-tier pricing, with a higher price for GDPR opt-in, and a discount for GDPR opt-out. This would, among other things, raise awareness of the cost of GDPR compliance as costs are explicitly passed along to the customer, rather than hidden by embedding it.
