My mom installed a tracking software on my computer! Help!?

Okay, my mom is a control freak. How much you believe in parents being strict does not matter to me. You do not know the heights my mom will reach to know my exact movements. All of my friends agreed. She has a facebook but she does not want me to. Well....I made one at my friends house and I trusted google chrome's incognito mode enough to access it at my house. The next day she demanded my username and pword and told me that she has a tracking software that detected it. Look I know I shouldn't keep stuff from my mom but I need a social life and you DONT know her. I was wondering how I can access the tracking software I believe to be SpectorSoft. Please dont give me the "Your mother knows best"
