Norah, so far today, I have had no problems.
I have no idea how to do a screenshot.
Yesterday I had "the website you are viewing is trying to close the tab", many times. It was from "Windows Internet Explorer". I thought it was suspicious?
In the little box at the very top of the screen, (address box?) it had "Adcash", where normally it would say Crossword Help Forum.
On my Android phone, I often get alerts saying, "there are problems with this site's security certificate".
Hope this info is helpful.
I have done a security check on my laptop for bugs etc and it is clean.
