So last night we are ready to sit down to dinner and we get a phone call from a friend. She is frantic, her husband came home to all these messages on the computer stating it was infected and the speakers were blaring and call this number to fix the problem. So what does he do? He calls the number gives them a credit card number and then allows them to take control of his computer! As this is going on his wife comes home and calls me to ask what she should do. At this point it is to late to do anything except pull the plug on the computer, call the credit card company and kill the transaction and I would keep a very close on my bank account and any other money accounts I have. I also told her that the best action now would be to reset the computer with a reinstall of windows, I would not try to clean up the computer.
The sad thing about all this is that I have told them repeatedly about such things and they even had a brush with this anti-virus scam a few years ago but that time the wife was on and she just reached over and hit the button and called me the next day. What gets to me is it always seems to be the same people who get this stuff over and over again! I have held classes on how to protect your self and preached to these folks and others about all these scams.
If you are running Windows (any version) and you start getting pop ups for you to install a program or call to have your computer fixed its a SCAM! If the message(s) are not from your installed anti-virus or anti-malware then you should treat it as a scam. Turn off your computer boot into safe mode and run a scan with your anti-virus and anti-malware. I would also clean the HDD up but getting rid of any temp files. You can use a program like Ccleaner to do this.if you don't know how to use the file manager to go in and clean up the HDD. Also NEVER, NEVER let anyone take control of your computer unless you know and trust them. OK I'll get off my soapbox now.
