Here is a twist that all the searching hasn't helped.
One of my sites is being marked as "suspicious - visiting this web site may harm your computer." Alright... Well searching the problem tells me I need to search all the files for nasty inserted code. I can't access the Dashboard:
The requested URL /wp-admin/ was not found on this server.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request
Has anyone had this double-whammy problem?
What should I do?
