    Default Beware the new windows 'SPECTRE' bug fix patch.

    Just experienced problems with the spectre patch from MS on windows 7,Intel I5 btw,machine would no longer restart cleanly,also dropped internet and god knows what else.

    Removed the spectre windows update that had 'auto installed' itself.

    back in business.

    not only affecting AMD's,despite what I could find.

    If you had windows auto installing patches,you've been hit no doubt.

    This gets really interesting with this addendum:

    A Redmond support article clarifies that "customers will not receive the January 2018 security updates (or any subsequent security updates) and will not be protected from security vulnerabilities unless their antivirus software vendor sets [a particular] registry key".

    Spectre affects all CPUs (Intel, AMD, ARM (used in many phones)). Meltdown mainly affect Intel and some ARMs, but Microsoft patch for Meltdown causing issues with AMD machines.

    Typical Microsoft

    Nvidia just released a new graphics driver, GeForce 390.65 WHQL, which has a security update against the Spectre variant 2 (CVE-2017-5753) vulnerability. Not sure about AMD drivers as it's a GTX 780Ti i use.

    Thing is,if you DON'T update with the patch,those WHQL drivers essentially are borked,as they would expect the update/patch to be applied.

    Note that this was on an Intel I5 system too,I haven't applied it to any of my AMD's yet.

    Yeah, but like I'm saying,the patch is also affecting Intel machines,not just AMD.

    Avast was the antivirus that set the registry bit BTW. There's a list in the 3rd link I posted,regarding antivirus,it's a spreadsheet that has all the AV vendors and if they set the registry 'bit'.

    Looks like i'm covered, using Kaspersky Total Security, Trump's favourite, so good to go, might still hold off though, don't really fancy a borked PC.

    Did you read about the performance hit from patching? 10-30%

    'When it rains, it pours', just keeps getting better

    I'm still back in the stone age regarding CPUs, i5-3570K but have it purring along nicely at 4.4Ghz so am reluctant to mess around too much, all this on an ASUS Mobo and i read the patches also borked ASUS' AI Suite which handles a bit of the overclocking and stuff, definitely going to sit back and watch a bit.

    ATM,I recommend everyone install noscript just in case. The fact it can be leveraged through the browser and java makes it a lot more dangerous and widespread than they first make it out to be.

    It's not infected, it's affected. If you have CPU - you affected by this vulnerability. There are patches (patch for Meltdown have 5-30% performance hit (games performance usually not affected much), patch for Specre is more workaround than patch), but patches themselves cause issues. Meltdown require binary, Specre works from browser - https://meltdownattack.com/
