back to article Windows 10 Anniversary Update crashing under Avast antivirus update

Avast has issued a rushed fix to stem blue screen of death action caused by an update that clashed with Windows 10 on some systems. The patched patch fixes a kernel panic caused by conflicts with a Windows 10 Anniversary Update on Intel Skylake Virtualization Technology machines. Microsoft's update sent some machines with …

    Did anyone actually test this?

    Also seems to have a distinct dislike of the nVidia Driver Experience program. Its not fatal- but the number of errors it throws up just isn't funny- and after the install, you'll keep getting popups about bad msvcrt.dll image files etc etc (there are a rake of them invoked by the nVidia drivers).

    This really is buggy as hell. I can't revert- because the main drive I use for o/s is a 50Gb SSD :(

      Seems like no one did test it. Hey ho, welcome to the modern world.

      I've decided to roll back to 7, and let MS get their buggy code fixed and working without involving me any further. Hopefully they'll see sense in due course and will make it more like 7 in spirit if not in looks. By then I'll likely be upgrading my PC anyway so will be getting a license thrown in whether I like it or not. Failing that I could treat myself to a Mac...

        You aren't. See the article the other day about drive-by installs? Notice how all the virus scare stories are about zero-days? AV doesn't work. It hasn't ever worked. It can't work because distinguishing "malicious" software from what comes out of big-name vendors just isn't possible, even for human intelligence after the event. AV is a gigantic scam. You are better off without it. Run as a normal user. Don't follow phishing emails. Don't install crapware you downloaded from a sharing site. In short, use Windows the same way you'd use Linux.

          Education and proper configuration and external firewall beats ALL AV for effectiveness. 30 Years of testing proves it.

          AV is part of the problem, not a solution. False sense of security substitutes for users actually paying attention and learning how to use Windows safely. UAC is also pointless.

        Criminals rob banks all the time - does that mean that a bank building is less secure than a greengrocer's shop?.. because, after all, you never hear of a greengrocer's getting robbed.

        Security is not a technology issue. The technology is just a tool-kit; it still needs to be used by a human. Windows has all of the same security measures as Linux in place to prevent privilege escalation or out-of-process access, and all the other nasty ways a piece of software can do something that you, as the IT admin, don't want it to do.

        But none of these protections really matter, because the easiest way to get malware onto any system, no matter how "secure", is to give the victim step-by-step instructions on how to install it and let them work around the system's security measures for you. Of course, you tell them that they're doing something else (like getting something for free), but the malware gets in there all the same.

        And if you target Windows with your ransomware, you've got: 1. a far bigger target population, and 2. a higher likelihood of getting your malware into a company that'll pay the ransom.

        I use OSX, Windows10 and Linux daily, and I don't really play favourites, but I do get fairly tired of the insistence from Linux and Mac users that their platform is somehow more secure simply because criminals have no real financial incentive to attack it.

          > Of course, you tell them that they're doing something else (like getting something for free), but the malware gets in there all the same.

          The thing about Windows is that there are (or were) designed in 'convenience' features that mean you don't even have to get the user to do anything other than normal operation. For example: simply inserting a CD or USB could run software on that media. Selecting an email could cause it to load an attachment and execute code (eg Excel macro or Javascript), downloaded files can be executable without further action, file types are hidden so knickers.jpg.exe looks like knickers.jpg and clicking on it executes code.

          Other systems just aren't that convenient for malware. The user must do something out of the ordinary.

      Re: Two questions

      "What the hell is Avast doing..."

      You should note that this was an MS patch to a previously working configuration. Avast did something that MS-in-the-future didn't like. Failing to test that scenario isn't quite as lax as you suggest. It depends on how fully-featured and documented are the kernel hooks that MS (presumably) provide for AV vendors.

      "Why is Microsoft allowing kernel patching at all?"

      Because third-parties like to install drivers for specialised hardware and don't like paying MS to write them? I know a fair bit of hardware can run in user-space once MS have provided a generic driver for the relevant bus, but not everything fits that mold. Notice also that if you have Administrative rights on a Windows machine in user-space it is only a matter of time before you can override any restrictions on kernel patching.

        ...the kernel hooks that MS (presumably) provide for AV vendors...

        'Patching the kernel' is not the same as 'writing a device driver'. Microsoft provides a rich, documented and free API for drivers to use to hook into call chains. I can fault Mcrosoft on many things, but not this. AV writers have a history of destabilising the very software they are trying to protect: I suspect Avast is a rat's nest of hackery, patching and general under-the-hood horrors. And they've been caught out. As ever with AV software, the cure is far worse than the disease.

        And 'a previously working configuration' doesn't mean all the running software (i.e. Avast) is going about things the right way.

      Re: Two questions

      Kernel/driver coding is HARD, and there is a lot of potential for unforeseen interactions.

      MS has actually stopped, beginning with 64 bit Windows, AV vendors (and certain other usual suspects) from poking around in the kernel arbitrarily. See PatchGuard / Kernel Patch Protection.

      Instead they have provided documented APIs for things like filtering syscalls.

      This however sounds like a driver for the Avast virtualization sandbox thingie. Not very familiar with it, but you can't really stop that without breaking VMware, VirtualBox, et al. as well.

      Windows 10 has so many malware like features its truely difficult to discern the difference.

      The problem is AV Vendors are also having a hard time distinguishing the difference between real Malware and Windows 10 Anniversary Update's 'New features'. Technically, many properties of both forms of malware are the same, its just the MS ones are seen as 'official malware' that route Private data through MS Servers.

      You could have exactly the same 'Windows 10 feature' i.e. installing an unrequested app (in the form of malware) routing exactly the same telemetry data through a third party server that would be flagged as malware under different circumstances, and there is your problem.

      Re: Real Users

      What is needed in these discussions is less juvenile Windows bashing, and more useful advice on how to make average users' Windows machine safe and functional with little or no user intervention.

      Remove the user from the equation.

    For Microsoft to send out some ransom-ware.

    Oh, wait, they already have, it is called Windows-10. Don't forget to send some $$$ for the next update that we will push onto your machine and ruin all your applications, causing you to spend even more $$$.

    Somehow I wish it were a joke, but from the looks of it, it isn't anymore. (*SIGH*). Maybe that is why I can get a call from someone being a "Windows specialist" wanting to clean my machine.

    Avast! is the problem here. They were recently acquired by AVG (yes, them) and since v11 Avast has rushed in (premium) Beta 'features', removed the RA tool in v12 and I now suspect the AVG codemonkeys are starting to have their way with the product as well.

    To be fair it was going down the tubes before AVG acquired them and AVG haven't made a product that I'd rate that even works on Windows since v7.5 on XP.

    Both companies concentrated on looking nice while adding yet another mouth to the rim of the cup that is your metadata.

    ......Microsoft in cooperation with their partner Avast have succeeded where all others have failed. They've achieved a totally secure computer environment..........while your machine is turned off and stays off.
