Hi, thanks for tips. I uninstalled everything I could find in my control panel 'uninstall programme' section but it still appears on my bottom screen bar as wanting to open. I find this sinister and would like to wipe it off. Even more sinister is the way it tricked me into downloading it. I was looking for a driver for an HP printer and it masqueraded as that on Google.
