Is someone in my computer?

[sarahs just another nothing.]

I've recently being cyber-bullied by a bunch of scum bags, on a virtual chat site called Habbo Hotel. They are 14, 15, 17, 18 and one is 21. They threaten to hack my computer and other crap. Our compyter mouse moves on it's own, sometimes I feel like I'm being watched through webcam. I checked our internet connection and it came up someone elses network ''Unindentified Network''. My sister was using facebook and Notepad came up with a msg saying ''dumbass''. Help?

A paper square and some duct tape over your laptop webcam is a great start. Post some empowering pics on Facebook and call it "GOOD". Moving on...girlie

Call the cops?

Do you have Windows? If so, make sure Windows Firewall is running, and start it if it is. Disable (or if it's not built in, unplug) your webcam. If the webcam is recording, it will probably have a light on, probably near the lens.

Do all of this, and if it doesn't stop, contact the police. It's entirely possible you have a virus, or your sister was just trying to scare you. Also, take screenshots of the threats.
