I received a call today similar to the ones above, However, I did allow access to  my computer and charged $149 for a Windows repair toolkit, security system, e-mail, data theft protection and anti rootkit, "malware" and "phising" thru Western Union. I am very concerned about my data now. I am normally level headed but they said they were calling from Windows Control Division and had  been alerted to the danger I was in regarding undetected viruses on  my computer.
I fell for this one and hope you can find this source for all lour benefits. He did give me this number and I didn't call it in time! Do I have any recourse? Can I stop credit card payment? It was Mastercard.

I got a call on 1/20/2012 from a girl with a strong Indian accent.  She also tried the scam of telling me I had numerous viruses that were flooding MicroSoft servers and that she was calling from MicroSoft to help me clean up my computer.  I was already suspicious but soon realized that without any action on my part, she was in my computer already clicking through various files!!!   I told her that my phone was going out and that I needed to call her back.  Amazingly she gave me her real number. She first connected me to her "supervisor" who was probably sitting by her side.  He also had difficulty with English but said his name was Robert Jackson.  He tried to steer me to the Teamviewer website to d/l their software and when I asked why MS was trying to sell another product, he hung up on me.  I did call the FBI and will try my best to pursue this.  First, Teamviewer needs to disassociate themselves if this is a sales ploy on their part.  Otherwise, the phone provider needs to help authorities stop these people.  I did call the number back and told the girl I had reported her to the FBI.  She started yelling like crazy and hung up.  I called back again and the "Robert Jackson" answered.  I told him I would try to see them both in jail!  I occurred to me that this may be a ploy being used to get control to computers to use for DNS attacks.  Probably not but I am not computer savvy.  Still, they work very hard to not have a real agenda and they are very savvy about what they are doing and the entire MS Windows system.

I would call Mastercard.  If Mastercard and other entities realize this is a complete scam, they will stop processing payments.  That is one way to get back at them - if the authorities are not interested.  I personally think this could be VERY dangerous and will do my best to alert all the law enforcement agencies tomorrow.
