Criminal hackers have spammed out emails which pretend to contain a license key for the desktop publishing program Adobe InDesign.

                       Their intention? To infect your Windows computer with malware.

                       The emails pretend to come from Adobe, in a noxious campaign which bears many similarities to the fake Adobe Acrobat Reader updatesspammed out yesterday.

                       A typical message looks like the following:                  

                                     Subject: InDesign CS4 License Key

                                     Attached file: License_key_ID[random number].zip

                                     Message body:
