Don't get caught in the free I-Pad scam!

Someone raped my friend's facebook info and sent me an email supposedly from her, telling me how she'd just gotten a free I-Pad and wanted me to have one, too. I didn't even want a free I-Pad, but I have a wonderful son-in-law who I'm sure would love one, so I began filling out the form, gave them my email address, then thought better of filling out the rest of the info. But, alas, once they had my email address, they had a pop-up that I couldn't get rid of, that froze my computer. Now, with the help of AOL's advice, all of my settings are off and the computer clicks and turns on as if it's crashing. My techie, Kathy, is about to hear from me.
