Valentine virus warning
Security experts are warning PC users to be on guard against viruses masquerading as Valentine's Day messages, which could damage computers.
"Computer users should keep a wary eye on any romantic messages received by e-mail, as many of them could contain malicious code," said US security firm PandaLabs after detecting an increase in a worm it dubbed Nurech.A.
The worm hides in emails with subjects like: "Together You and I," "Til the End of Time Heart of Mine."
People who open an attached file such as postcard.exe can end up infecting their computers.
