I was at a hot spot (public library) and got online to check mail...the connection sucked and kept closing down the browser, so I diabled the connection.  However around an hour later I noticed that there was this little icon that was popping up saying "sending files to computer" I saw it pop up twice and the third time I just unplugged the computer and shut down.  It told me something to the effect of "another computer is logged on, are you sure you want to shut windows down, they may lose their data" Heck yes I want them to lose their data I thought as I pulled the battery out of the computer hoping that would render the hacker helpless.  I piled my stuff in my bag and one smart looking high schoolish / college aged kid leaned back in his chair and looked around, looked at me and got all nervous...gotcha.  But not really, because what was I going to do?  Confront him?  Not really...owned!

Oh so here's the deal...I usually use a Mac so I never really have any problems like this.  I was using my husband's PC because the Kaplan disks don't run on macs (thanks for looking out for the rest of us Kaplan).  So,

1. How can I find out what files were "sent" and how do I protect this computer.  I need to be able to take it out and as I stated above, I had disabbled the internet connection.  Oh and files sharing was off.

2.  What now?  do I have to change all the passwords on the computer?  could something have been "sent" back to me?

Thanks so much in advance for any help/advice,
Nicole
