The OP says that using right-click to copy a link to google.com gives instead a link like:

http: // api.viglink.com/api/click?key=8eb8c964d...

But I am not experiencing that with a right-click in either Safari/Mac OR FF/Mac. He mentions Safari not being a problem. I find that FF/Mac isn't either.

EDIT: Any chance that they have disarmed this after getting all the bad press (at least on HN)?
