Pardon if I missed an earlier discussion on this particular aspect of Wannacry. If so, please just post a link to the solution. I just obtained a newly reconditioned PC, running Windows 7 x64. I ran Windows Update almost as soon as I got home and got the PC up and running, which identified a number of important and optional updates. I installed all the important ones and several of the optionals and, after several reboots, I installed and ran Avast Free. The Quick Scan came up clean. However, the Wi-Fi scan declared:
"This computer is vulnerable to the popular 'WannaCry' ransomware worm using an attack known as "DoublePulsar" - there is a vulnerability in the Windows file sharing service which allows attackers to remotely take over the PC."
I followed the advice provided and downloaded the "March, 2017 Security Only Quality Update for Windows 7 for x64-based Systems (KB4012212)" from the Microsoft Update Catalog. However, when I tried to run it, I received the message, "This update is not applicable to this computer." On the chance I selected the wrong file, I downloaded and tried to run two other March security updates related to Windows 7 (x64 and x32). I received the same message each time.
At this point, I can't tell if I am getting a false positive from Avast, if I am simply choosing the wrong file to download, or if something has infected the PC that prevents the patch from running. If I missed the post with the solution, please provide a link. If not, I'd appreciate a suggestions on how to proceed from here because I'm feeling both stumped and a bit vulnerable. Thanks in advance.
