Sophos is warning computer users about a widely-spammed out email teaser promising a trailer of the film “Pirates of the Caribbean 3: At World’s End” – and the chance of free tickets.

The email, which contains the familiar skull-and-crossbones logo of the popular film franchise, appears to have been targeted at movie-goers in Europe and North America.

Rather than a trailer for the blockbuster movie starring Johnny Depp, Keira Knightley and Orlando Bloom, the email has a copy of the Troj/Yar-A Trojan horse attached. If cinema fans run the attached file they are shown a fake error message, and the Trojan horse downloads malicious code from the internet while disabling anti-virus software.
