You can also get fake warnings popping up on your computer telling you to call a certain number. Don't call it. Too, even if it says "Verizon Support" with an 800 number, it's a fake. Get all the numbers you are supposed to call for help and info from the place where you got your phone, computer, etc. and DO NOT call other numbers.
Good Point! I had forgotten about those. Another thing I had forgotten about, and I think is just as or more dangerous, is that there are some area codes that if you call them you are charged an enormous amount of money just because you made the call. I've heard of this in the past and I don't know what those area codes are but the scam was that the scammer would call and people would call back the number wondering who it was never realized that calling it would set you up for a charge due to calling that certain area code. Sort of like a 900 number.
This particular scam may have been addressed since I first heard of it and the Government may have enacted some laws that prevent the phone company from automatically billing for calls to the specific area codes but I have to say I'm not sure about that at this point.
Yet another scam, I have heard about recently, is where the scammer calls you and ask some simple question that you answer YES to all the time recording your voice and then takes your YES off the recording and uses it to set up accounts in your name and to their benefit. Again I haven't heard too much about this one other than a caution not to answer yes or say YES to an unknown individual. To me, this would be one of the most difficult (for me) to avoid. I hope it's not true but somehow I feel it is.
