DeVry in Kansas City uses this service for their wireless internet. They should be using WPA-Enterprise in the first place, but it wasn't a big enough deal for me until now. Today, I logged on to the wireless to use the internet to do my math work. After I logged in, it ran a Java app, without telling me what it was doing. Once the app loaded, it was immediately apparent it was running some sort of scan on my computer. This may simply be a virus scan, but without any mention of what was running there was no way I was going to trust it. I immediately closed my browser to stop the app from harvesting any data without my permission. Edit: I have looked into this scan, and it turns out it is completely intrusive, looking into my Windows registry settings, and anti-virus settings. As far as I can tell it looks at every single program I have installed. I have no way of knowing if it is keeping a log.
