It has taken me several days to sort out the problems I have been having with my computer, but I think now it is sorted. The biggest problem was PlusHD.9. These are the scum of the internet they give you an option to opt out but it doesn’t work. Anyway having removed over 200 files and associated entries the problem I have been seeing here appears to have been cured. Please let me know if you receive any more spurious emails.
