Gee, that's not suspicious at all

That clearly looks like someone tried to force the trunk open at some point, and given the lock is on it when the picture was taken it stands to reason there was something or someone in there at the time. What do you do when you see something like that? Call the police?

It's always a good idea to be suspicious of any strange behaviour on your computer. It might be innocuous (like Windows Update slowing everything down from behind the scenes) but it might also be a sign that your computer has been compromised. The only way to find out is to investigate further, but that won't happen if you don't at least have some suspicion about it.
