Film and Communications industries competitor hackers

[ShackleKey333]

I am a director and screenwriter. Where I am has massive security and if I use my laptop at any point to login to check my email, my password is known. i think that they erase emails from my account so that the only ones that contact me are not a competitive threat to them. I do not even have any security on my laptop. It feels like they have so much money and development is my little computer really going to have a chance with some lame software when they have offices of people.
There is one production company site where they rummage through my computer when I visit and the few times I have gone there my computer suddenly crashes. I have even had them in my PDA.
Is there anybody here that is fascinated by film production that may be interested in lending suggestions to me.

Right now my main concern is that emails are received properly, my site viewed properly (I saw it not accessible on the set of a production) and that I receive incoming emails properly even if competitors login and erase them. Thanks!!!
