Thank you for the Root Alyzer.
I did download it and execute it from the zip file on the desktop. How do I complete the installation in order to execute it in the future? I did not see it in the Spbbot list of plugins.
I did not find any problems with the quick scan. I got 36 entries like this one from the deep scan. They all dealt with System Certificates. There was no explanation:
Key:"Hidden registry key","HKEY_LOCAL_MACHINE","\SOFTWARE\Policies\Microsoft\SystemCertificates\?????k\",""
