Well .Gr replied with "read our privacy Ts&C's.
I did,but still do not have an answer to my precise problem. I have tried Adaware also. No joy.
It seems whenever I 1st boot my pc the GR homepage loads even though spybot throws up the usual warning about blocking Avenue A download, but after ,if I'm lucky, a couple of page refreshes or different page, same prob...page wont load apart from the big banner ad up top with blue background on rest of page+ usual block download warning.
I have tried contacting Neilson/Ratings ,for which a link appears in GR T&C's (they seem to provide a stats service for GR.) to try to find out if they are responsible or aware of Avenue A Inc. Frustratringly their contact us page does not work properly & refuses to submit the query. I have Asked GR to send my Query on my behalf.
