F-Secure SAFE and KB4056892

F-Secure SAFE and KB4056892

Using F-Secure SAFE on Windows 10 Pro (v. 1709); MS released the KB4056892 critical security update  which fixes the Intel CPU Problem. 


MS adviced asking the Antivirus manufacturer to ensure that there aren't any compatibility problems. 

Are there issues? Or am I safe to update?



  • Ben - can you make this information more widely available? I looked at:


    F-Secure Twitter - nothing

    F-Secure Facebook - nothing

    blog.fsecure.com - nothing





  • F-Secure SAFE just got the update and KB4056892 started downloading after that.

    I have updated my ISP operater supplied F-secure Anti Virus product but no Windows 10 update is made available up until now. I suspect this sub-branded F-secure product isn't updated with the latest sollution to Spectre and Meltdown-compatitbility yet. Can you investigate this? The product is called "KPN Veilig", where KPN is a large ISP in The Netherlands.

  • I did receive the windows update after the SAFE update...

    I also used F-Secure for my windows 8 pc. From Contact Arlo support, I buy this antivirus for my laptop. From there I also read that these are not a big problem. You can read the latest update and problems from there.
