I need help. Can someone access my files without me knowing it? Is there a program that allows someone to have that much power? This is how it goes. My cousin fixed my CPU for three days. Now, I do not know if she had installed something that will monitor my every move. For example, if I record a video will she be able to see it that easily? Please answer fast. I am so worried that someone has violated my privacy. Email me! or answer here.

It is possible. If she had your computer for 3 days she could have copied the whole drive. In regard to future actions she has to get access to your systems while you are connected in order to monitor you. The best for occasional connection is a keyboard logger. When you boot your system check what programs are running. Don't leave sensitive items on your computer. Learn how to fix your own computer. Don't leave your computer connected to the internet. Have a good firewall.

I use a Norton antivirus firewall. So will she able to monitor me from a remote computer whilst I am on my computer.

Only if she opened up your firewall to allow herself access. Otherwise, no. Good luck, -SN
