PMS can only access files (local and remote) that the logged in user running the program actually has access to, and it will only create logs on the running machine, not on the remote machine. He would have had to have direct access to your files already before being able to access them with PMS.
As such, this is not an issue with PMS, and while it sucks that this happened to you, it is outside the scope of this forum. I'd recommend going to a security related forum for help getting those logs checked.
I provide NO application support via PM or email, so please post your question to the forum per the Forum Rules
