My computer receive a pop up that my computer is infected by a spyware or virus, and there is a program "Microsoft Essential Security Alert" that to be bought and to stop the virus/spyware. I put my credit card number but it was a scam only i was charged $89.95 and my bank won't dispute it because they said it was valid. I didn't even receive the item that i was charged. I hope no one else will be fooled by this.
