SCAM!! SCAM!!! SCAM!!! WANTING MONEY, AND POSSIBLY TO HACK YOUR COMPUTER!! BEWARE!!!

Have been getting calls from this number for months.  Friends have also received calls, and the caller is obviously from India, can hardly speak English.  I have threatened to report them, told them not to call back as we are on the Do Not Call Registry, told them that it's a scam, etc., etc., etc....So, today they called again.  I decided to go along with them to see what they were actually after, as they always try to tell you that there are dangerous files installed on your computer that could make you vulnerable to a hacker. You know....scare tactics.  Anyway, I pretended to be dumb, let them think I was going along with their instructions, acted computer illiterate, and kept them on the phone for about 20 minutes.  The first guy transferred me to a second guy (an "expert"), who was going to connect to my computer, remove the harmful files, and, in short, charge almost $200 for doing so....I had wondered what the purpose of the scam was...So, at that point, I asked him to repeat what he had just said, then told him "no", and proceeded to inform him that my computer IS safe, that I actually KNOW a lot about computers, and that there was no point in wasting any more of his time or mine.  It's a funny thing that, if you let them know that you are on to them, they become aggressive, rude, and try to out-scream you...
