While I was away for 3-weeks, I suspect that someone in my family got into my computer and nosed around my files. How can I track where with went and what information they may have accessed? I've since protected myself with many passwords.

Hi, featherly!

Is this a PC or an Apple/Macintosh?

Thanks!

Mostly you can't unless there have been changes made. As for web browsers you can check history but as far as files unless you go through every single one and check for opening dates etc its almost impossible without having software on it before to monitor it.

You could do a search for files modified within the date range you were away. It won't be 100% accurate but it will be a start.
