Hello,
i have a question. I apologize as a precaution for my not so good english.
I was in the process monitor by accident. there I saw the cgminer is permanently connected to
3dns.adobe.com.
what does that mean?

CGMiner is connecting to 127.0.0.1 (localhost)
In your HOSTS file in Windows you have specified 127.0.0.1 to be 3dns.adobe.com
You must of installed some pirated patch or crack for some Adobe product which needed to do so.
