POLICE in Dorset have issued a warning about scam emails claiming to be from the Royal Mail.

The emails have attachments which contain a virus and victims are then asked to pay a ransom to remove it.

“By following the instructions within the email the CryptoLocker virus is subsequently downloaded to the victim’s computer. This virus encrypts files on the victim’s system and requests a ransom be paid in order for the files to be decrypted” said a spokesman.

"Additional incentive is added for early repayment as the ‘ransomware’ states that the cost of decrypting the files will increase the longer the fine is outstanding.”

Members of the public are urged to avoid opening attachments from unsolicited emails and to examine the quality or pictures on emails. Anyone who believes they have been a victim of fraud is urged to report it to Action Fraud on 0300 123 2040.
