Were you able to run Emergency Kit Scanner?

It seems to be good?
C:\Users\Gernot\AppData\Roaming\NsCpuCNMiner is not more visible.
good deal

Any more step to do? If not, i will deinstall most of the software.
Yes, please run the Emergency Kit Scanner, this should finish things up.

What do you think, are my passwords and personal files leaked?
Hard to say but what you can do is to take precautions now.
From a known clean computer, change your passwords to delicate web sites that you login to.

Im surprised that even if i immunize the system every now and than and do my updates and checks i got this crap. And its amazing how much tools you recommend to run- Seems like Spybot is not enough? -.- Thanks so much for your effort and time and interest in solving it and offering your experience.
Your best bet, and anyone else's, is to learn about layered security. There isn't a security app invented yet that can completely do it all.
There are many that do a good job and protect as well as they can but, I can list a prevention's list when we finish.
