Dyfed-Powys Police are warning people not to fall victim to a telephone scam which is currently targeting people in the area.

The force has had a number of complaints from people who have received phone calls from callers saying they are Microsoft Engineers.

The caller states that there are viruses on the victim’s computer and the system is running slowly because of this.

These can be fixed if the victim logs into the computer and follows the callers’ instructions.

After identifying that the system is infected they ask for credit card details for payment for software and are very insistent.

Karen Burch E Crime Wales Business Officer said that the changes made could disable the anti virus security installed and result in files being deleted.

"Our advice is simple," she said. "Do not give personal information to strange callers.

"Microsoft employees do not ring their customers. Do not access your PC on the directions of a strange caller.”
