I have a dual boot system (WinXP / Mandrake 9.2). I was using WinXP the other day and just as i was browsing the internet i got one of those annoying pop up windows. The thing was that it had the following information in it: my ip address, the os i am running, my isp and even a list of my folders on my C: disk. Is there a way to prevent other people from acquiring the above info or does Linux takes care of this by default in the default installation. I no nothing of Linux security and have no knowledge of programming or scripts.
