How secure is the Internet?

The discussion about how secure we are on the internet? Well, after hearing about how not so private and secure the internet really is? This has brought a lot to my attention on how much privacy we really have when we are on the internet. I know for sure I won't be using my webcam ever again. I have to say that it's so violating on how hackers can get into your computer and get all your info online. I know now I do not leave my computers on anymore. I had a discussion with my family about this and they never thought that this could ever happen.
