This web site gets flagged by Trend Micro every time I start up my web browser, even though it is not in any of my tabs (perhaps because TM blocked it).

I can't find the source of this, and Google only shows one site hit for this, with no info.

Anyone here who can spread any light on this, and how to get rid of it?

Update: it seems to be a tracker for web site visitor tracking, now I'm just wondering how to get rid of it.
