0ne time, I and my sister were fooling around while accessing the same website at the same time. We would copy each other's steps in accessing the site. Then her laptop suddenly stopped working. My cousin, who is a computer technician and at that time visiting us, He took a look and informed us she got a boot net attack. This could have been prevented with a popup blocker. My pc has one that’s why it was not affected. There are so many new things that we really need to know.
