I feel that I should share what I just experienced. I am currently at work and was taken back by what I heard from my wife…
She called me saying that she had a call from Microsoft saying that her computer has been sending malicious information and proceeded to connect to her laptop remotely. I asked her if she gave them her password and she told me no. they were able to connect to her without any authorization. They then proceeded to walk her through some settings that would need to be changed. My wife wasn’t suspicious until they said they could do it for $199. that is when she told me she hung up the phone.
Here is a link from what I googled:

I had my wife unplug our router immediately to stop any remote connectivity to our network. I called our ISP and had them change my IP address. Word to the wise…If you aren’t the only person that can access your home network/internet. This is information you should know and pass along. I get to go home and gut/clean out my laptops that are on my network. I just hope the xbone isn’t affected.
