Ron, do you mean this thread, if so, then I'm afraid it's not clear what the problem is, you have successfully downloaded and installed Chrome and when you open it you get the error? If so it would appear to be trying to logon using your Google ID (if you have one), I'd guess that you've possibly tried Chrome before and it's still in a cookie somewhere. Just type www.bbc.co.uk (or some other site) into the address bar and see what happens.
My point re. 'dubious' download sites is that they don't host downloads for free as bandwidth costs money, they usually add either advertising or toolbars to the installer or even malware and the like.
