Am I being hacked?

[MarleneD]

Last night when I wanted to shut down my pc, I had a similar warning message to the one below pop-up:

"If you shut down other users will loose their data"

I don't remeber the exact words - as I was in a panic state.

Is there a way I can find out if I am being or have been hacked?

I have a ADSL connection - win XP Pro

Do you have multiple user accounts on that machine. With XP's fast user switching enabled, this will happen if a previous user has not logged off. If you have an account with administrative privledges, you can see what users are logged on in the Users tab of Windows Task Manager.

I am the only user on this computer.

Thanks for the tip on how to find which other user is logged on the computer

You can lookup all open connections on your pc.

start, run, cmd
Netstat -ano

This will list open connections and the pid associated with the connection. Then you can compare the pid number with your running processes

Are you running a home network with other PCs and a hub/switch? If so one of them has a connection to one of your shares.
