Graham Cluley, senior technology consultant at Sophos Anti-Virus said: "While Klez refuses to go away, a new entry this month is Datemake - a type of malware known as a dialler. It is programmed to dial a premium rate telephone line, typically with the intent of gaining access to adult material. Businesses should apply strict computing guidelines to prevent getting stung by a huge telephone bill and embarrassed by these seedy programs.

"The WTC Survivor hoax continues to fool many computer users. Indeed, a newspaper in the United Arab Emirates has recently warned readers to be ready for imminent attack, " said Cluley.

"People who receive this hoax shouldn't believe everything they read. Instead of forwarding the warnings to everyone they know, they should ask their network managers for advice."
