Picture appear after erase HD Macbook pro

[Anubiz]

So i decided to erase de HDD on my macbook pro and reinstall yosemite, after 2 weeks of normal work, suddenly a picture appear in my trash can, an old picture from 2012 (not important) with no name only a lot of numbers in the title, so i freak out thinking that i have been hacked or something, so i erase again and reinstall yosemite, and erase the free space. Please I really need some help so i can be more calmed and stop thinking that i have been hacked, and someone stole my private files.I called the mac center and explained what happened, and they told me that they never heard something like that, but a hack thing would be very difficult. Is this a normal bug from mac computers?

I don't use iCloud and all cloud stuff

Do you have any external drives, or a flash drive attached? The picture might be in the trash of the external volume.
[doublepost=1464045670][/doublepost]Might also be in your DropBox trash.

I dont remember if that day i had one attached, but that could explain the problem. But if i did not have the external drive attached, what other thing could do that Weird thing??, thank you For the reply

Most likely was an external drive. Might be DropBox too, or any sort of network or cloud storage.

I dont use Any of cloud storage, do you think it could be a kind of attack ? Or something bad to steal files?

I doubt it. It was likely in the trash on a flash drive or external drive of some sort. If you have emptied the trash and it disappeared, I wouldn't worry about it.
