Delete app from my laptop

I made the download of the Sophos Endpoint App and this *** block all my laptop and websites, i don´t have a login, and to delete the app ask for a password of protection wich i don´t have. I was going to work from home, where i work they start to use this program, but after this problem i got so angry, i just want to delete the app from my laptop. I can´t disable nothing because this *** app. I never saw a webpage that don´t have a phone or e-mail.
