The Nebraska Attorney General’s Office is warning the public about a computer tech support scam. Jon Bruning says his office's mediation center has received more than 10 reports this week about phone calls from people falsely claiming to represent Microsoft in order to gain access to sensitive information stored on computers. The caller claims a security threat has been detected on the resident's computer and offers software available for download or to directly update the consumer's current system. Consumers are then routed to dummy websites that allow scammers to remotely access their computers.
