    Reproduction steps:

    install product, update it

    reboot OS

    Actual result:

    Before the first reboot, everything work fine.

    after reboot, avp told me there is no hardware support of virtualization technology, and I should change a device which support hardware virtualization.

    Expected Result:

    hardware virtualization based protection should work fine, there should not be any alert about it.

    I found that may be the bug in some AV modules that caused the problem

    I reinstalled the product, than reboot without any update. there is no alert about virtualization

    Than I ran a databases update and reboot OS, after the reboot, alert about vt is not available appear.

    I collected the entire traces begin from the product install till problem appear.

    1 install product

    2 reboot

    3 update product

    4 reboot

    5 problem reproduced.

    @xzz123, hello sir!

    can you reproduce it on new version? 

  • [2018] Titanium BT


    Not reproduced.

    But the situation has changed.

    Quite a long time ago, I report this problem: https://bug.kaspersky.com/issues/5846

    at that time, there was no problem with hardware Virtualiation.

    On about 2~3 previous beta build, I somehow able to install product with secure boot enabled, And here came the hardware-virtualization problem.

    This cuurent build .5.852, I again not able to install the problem with secure boot ebabled. And the hardware-virtualization problem disappear.

    I do not know the relationship between two problem. But since the environment has changed, I do not have a clear answer for your question.
