How are we supposed to tell whether Microsoft has fixed the vulnerability on individual computers? I have Windows 7 Professional. I see no indication that Microsoft has made available to me any update that would fix the problem (i.e., my last updates were installed more than a week ago, and I see no sign that new updates are ready for me to download and install).
I have Kaspersky as my main AV, but apparently I still receive updates for Windows Defender as well. Some months back, when I tried to turn off Windows Defender, Microsoft kept telling me I should turn it back on, so I did. To my surprise, WD and Kaspersky don't seem to interfere with each other. But in light of the news of this latest vulnerability, should I try again to turn Windows Defender off?
