"Despite warnings, users received some unwelcome Christmas presents in the form of new viruses such as Hybris-B, Prolin and Navidad," said Graham Cluley, senior technology consultant at Sophos Anti-Virus. "Viruses such as these are increasingly using psychology to tempt users to open attachments and everyone's New Year resolution should be to do a double-take before they double-click."
