Hi Nick and Howard,
I think different anti-virus software along with their settings and updates behave differently on different operating systems. I am glad that it seems to be fine for you, Howard and various people and I can equally understand the observations and/or concerns raised by others, which in turn I have raised with SIEG, along with my suggestions to them.
If anyone feels uncomfortable in proceeding with a link, they should simply follow the advise from the anti-virus software which they have installed.
