Does this sound bad?

I’m a student employee at my college and I work in a room with computers. I’m usually by myself in there. Well yesterday I went into my boss’s office to file for her and she asked me how my vacation was and everything seemed normal. But then before I walked out she said she wants to come in sometime this week while I’m working to go over something she found on one of the computers in the room and something she didn’t find on one of the computers. She says she is busy this week so we planned a time. It sounds kind of cryptic and I don’t know what she means. I don’t really know what that means but if it wasn’t something serious/bad I feel like she would have just told me right there instead of planning a meeting. I’ve never done anything I’m not supposed to on these computers but I do surf the web a lot if there isn’t anything else to do (but I have been told by my other boss that this is okay to do) and I don’t think she would have access to my history anyway. Does this sound bad to you?
