Last Friday (09 Mar) I was trying to get into the "back office' of my website and a message kept coming up that "hackers are attempting to enter your site". I tried getting out reloading, etc. Same thing again and again.
So I contacted Site Support and told them of the problem. It was not more than 35 minutes after asking me a question or two, they came back and said try it now!. I got right in. Whether this was malware or virus, I don't' know and really don't care, all I know it was a serious problem.
So I left my hat to WAs' wonderful Site Support!
