EDMONTON - Police in Winnipeg are warning people to be wary of telephone scammers pretending to be computer fixers.

Police say a victim told them about being contacted by a someone who claimed to be from a firm named "P.C. Doctor."

The caller updated the victim's computer security system in return for a credit card number and a charge.

The scammer wasn't finished there, later calling back to say the computer security package didn't work and that a refund was in order.

The victim then filled out a refund form with personal information and a credit card number, and was then hit with more fraudulent charges.
