Dear Lad, I fear you may have been well and truly hacked.
Since logging on at more or less 1700 hours your time, our time, I am getting constant messages to allow "cookies" from sites that have nothing to do with the MLU Forum and in a couple of cases I get the ad or popup anyway in spite of my protection software.
As an example, and not putting any blame at all on this forum, I ran my normal scans twice within about a half an hour and got multiple "hits" indicating someone is trying to infiltrate my personal computer.
Time to contact your provider?????
Really not trying to make problems, hope it gets sorted out.
Bill
