Hi - this is Ken from TinyCircuits, thanks for mentioning that, it's the first we've seen it. Seems to be a redirect on search results, I'm looking into this now. It seems if you go directly on the forum you can find the topic, but not if linked in from Google. Hope to have it resolved quickly.
This is Ken again - thanks again for pointing this out, we have gotten it resolved and the forum is cleaned now. There was a malware redirect on links coming in from search engines.
