I seriously do not think a legitimate company is going to use a DNS server named "proxyus.stealthy". Instead, I suspect you have been hacked, like the rest of us. You should definitely turn off TeamViewer at the minimum. You should not have it launch automatically on start up. You should go to advanced options and click the option to "deny all incoming connections". You should remove yourself from being included in anyone's account that would allow your computer to be remotely accessed by anyone, anywhere. You need to go through all of your settings one by one to make sure you are as secure as possible. The way I handled it was to completely uninstall TeamViewer. I cannot risk them connecting to me AGAIN and doing what they have done to others who are reporting the hacking. (PayPal, Amazon, etc). You should go to the TeamViewer Facebook page and you will see that there are a whole bunch of people writing in about DNS issues, and all sorts of things. Reports from all over the world are posted there about the TeamViewer service being"down". This is happening right now... as I type this.
