I've had a search, but couldn't find anything, so asking fresh.

I was alerted by my network administrator that my computer was attacking our internal network (port scanning).  Tracing a few ideas and different tools (especially TCPview) I eventually found my browser scanning each port in turn with connection to static-ip-188-135-101-169,inaddr.intergenia.de  This is the host site for bitcoincharts.com and as soon as I close that window, the port connections stop.

Has anyone else noticed this or have a better explanation why this address is scanning?

p.s. I have asked them for some tech support on this too.
