Stevo, does it happen after clearing cookies and cache? Does it happen with another browser?
I see little point in me reading this forum if people won't follow the instructions in the post at the top. Every single question I have to ask the same things over and over.
You can connect as many powerlines as you like. The one I linked has one that plugs in to your router and then the wifi one can be placed somewhere central in your house. You can add another where your xbone is. They also do ones with a built in 4 way switch.
I unlikely it's coming from this site. Have you read the thread at the top of this forum called "PLEASE READ THIS BEFORE YOU POST IN THIS FORUM"? I need you to follow those steps and post the information requested or I can't help.
I suspect you've picked up some malware from somewhere. It's hard to advise further when I don't even know what browser or OS you are using.
No they think you're going to go and plow it into a Bugatti Veyron, write it and your van off, then kill the occupants of both.
Well, they don't actually think it's that likely, about 40/1.

It's a system restore image. It's Debian. Steam said you'd need to be familiar with Linux installs to try it.
Use the Debian install method and choose "Advanced". If you are familiar with Debian installations it should be easy. I have to say "should" as I don't have an Nvidia video card so I've not tried it myself.
If you are not familiar with Debian installs, I'd wait until they release a version with a consumer installer.
