Last night I could not open either of my web mail accounts to check for emails. Google search had me to go to tools>internet options>Advanced and in the Security section, I had to check mark the 2 SSL and 3 TSL options. Then my web mail accounts could be opened. I do not recall ever marking those before. Perhaps, and I would not know, they were previously checked but 'something' removed the check marks. I had no malware reported per Malwarebytes. I have had no trouble since.
As always, TIA for your replies.
