I'm on the road a lot and utilize the hotels wifi spot. I'm wondering if someone could get into my system without my knowledge. I use spyware doctor for viruses, malwarebytes and spybot. I have the windows firewall, and spyware dr has a feature called threatfire. Should I be concerned? I woke up this morning with the little icon in the tool bar a new device has been installed and ready to use. This icon shows up at home when I hook up my printer to my laptop. I was surprised to see it this morning (I'm traveling). I went to sleep and didn't disconnect to the hot spot before going to bed. I'm hoping this is just a glitch in my toshiba laptop.
