Hi! Was on an open wifi in Greece and my computer said that someone is using my wifi-address. What can have have happened and How do I protect my content? Did not have my firewall up. Appreciate response. Thanks!

On a public WiFi someone captured your wireless traffic and IP address. Always keep the firewall up and running. Check into setting up a Virtual Private Network, VPN, so your machine is hidden when on a public WiFi.

Big thanks for response. Had my fire-wall off. Could someone have gotten to content on computer or outgoing traffic or both? Feel stupid - have no set my computer on and will do the VPN. Anything I can do at the moment or just keep my fingers crossed? Big thanks for response!!
Most likely scenario is capturing wireless traffic - if you sent any credit card or account information over that WiFi, change all passwords and notify the banks that your cards may have been compromised.
When you turn the computer on, turn off the networking so you do not broadcast a wireless signal.
Go to Finder, Applications, Utilities, and run Activity Report and look at the information showing for CPU, you will see a panel that shows the processes that are running. See if anything in there looks like software that captures keystrokes, spy information, anything suspicious. It is less likely anything was put on the machine, more likely that they were capturing data transmission.
You can also use VPN.
One really good company is called Hide.Me
Good luck!
P.S. Public wifi is usually not secure at all
Thanks - lots of funny stuff on the CPU. Some with my id but something with an id called "root" and names I don't recognise. Not sure if good or bad. Can I take it away? For example an id kernel_task. Strange...
/Thank you again!!
NO, don't touch those, you cannot end them anyway. Root is the ultimate owner, or super user, of everything associated with the operating system. Kernel task is the operating system, the actual core of the Unix operating system which is the basis of Mac OS X is called the kernel, as in the kernel of a seed...engineers are so creative in naming things
Other ther names of processes are wheel, daemon, your ID, so things the may look strange are ok. Any that strike you as questionable, just ask.
Some of the other legitimate process owners are networks, spotlight, coreaudiod, usbmuxd, iconservices, locationd, netbios, the majority of the processes will be owned by root or you. So those you can discount right away.
Someone is using my IP address
