Can you help please? I keep getting the following message pop up: Cannot Guarantee authenticity of domain to which an encrypted connection is being established. Application: Microsoft Windows Operating System URL: Ion21r2msedge.net Reason: Invalid name of certificate, either the name is not on the allowed list or was explicitly excluded. I believe the URL seems to point to a Microsoft Edge Server, but don’t no whether it is legit. Having run Superantispyware system investigator it shows up 4 invalid .dll files and a lot of unsigned .dll files related to Windows system. This is just a few of the many unsigned .DLL files the system investigator found CORTANA.DLL, CORTANA.EXE, HXACCOUNT.EXE, HXCOMM.IPC.PROXIES.DLL, HCOMMODEL.DLL, HXOUTLOOK.DLL it flags them as Microsoft Corporation Unsigned Digital Certificate not present or unavailable to verify.
