I have a serious question and don't really know where to turn right now. I'd just like to preface this by saying that I know a fair bit about computers, I'm not clueless. I started up my computer and went to go open the terminal window so I could start Hamachi. Upon first glance though something was wrong. The login name of the terminal window says someone else's name (I wont divulge for privacy). I googled this and found this person on Facebook. They go to my university. It says NOTMY-NAME and then shows my normal directory. (obviously with said name). Does this mean that the person has root access to my computer? Should I reformat disallow them access? Should I be worried about key loggers? The only shared folder I am running is to my public folder. It has typical permissions set up of read only except for me. There are no services except for Hamachi running openly. I have a password on my computer set upon any time it goes to sleep. I have a password attached to my account. Interestingly enough under the shared folders preference pane I can see this: I again removed the persons name. That is a domain of my university, however when I try to connect to that share I get it is unavailable. Can anyone help me or point me in the right direction? I'm really freaked out right now.
