I'm a newbie and I'm concerned about the safety of the files in my laptop. I recently deleted some confidential files, and I'm wondering if it is possible for someone to access my laptop via wifi and then perform some file recovery steps and gain access of my "permanently" deleted files.
You see, I use my laptop at school a lot, using the school's wifi. I started worrying when the technicians asked to borrow my laptop so they can "set it up", and then gave me the password. I am worried they might have installed some remote recovery programs that they control over the wifi i'm connected to and recover my "permanently" deleted files and send it to their computer without my knowledge.
IS THIS POSSIBLE? (By the way, my laptop's OS is Windows 7 Starter)
