Thank you. I will do so later today. I also submitted a problem report to Microsoft.
I have a Windows 10 laptop running Windows 10 Insider Preview. While 1959.1001 (rs_prelease) was installing, I received a message from Kaspersky Security Cloud. Is this a false positive? Windows Update (Trusted) is attempting to get access to malware Detected: Trojan-Banker.Win32.Gozi.isw Location: C:\Windows\Softwa...\pwsso.dll Cannot disinfect the detected object.
