Thanks for the two responses, which are much appreciated.

Well I have run AdW and that seems to have cleared Hola from my system, although I seem to have lost all my Google settings. I did notice however that it was still listed as a toolbar option within my browser setting, but I have now deleted it.

I have also run Zoek and that has produced a report but doesn’t seem to do anything else.

Is there anything else that I should do?
