I got rid of AVG because of the possibility of clashing.
I've run Nod32 twice, not yet in safe mode, the 1st time if found 3 "Things" the second time none.
The pop-up windows have almost disappeared.
The seemingly random "This program cannot display the webpage" thing is annoying but at least I'm online and able to tweak and repair.
I realise now how stupid the title of my thread is, instead of "post" read "with"
My next step is to get that spybot S&D doodah up and running.
Bless you all guys, it's not over but you have given me a firm shove in the right direction.
