More malware that plays on people's fears over swine flu has been circulating online, security experts have warned.
A malicious file by the name of Novel H1N1 Flu Situation Update.exe has been spreading in emails, researchers at security firm F-Secure said.
The file poses as a Word document and if it is opened will install a keylogger on your system.
"The document file that is dropped gets automatically opened by the malware, causing the user to think they really opened a Word file," said F-Secure's Mikko Hypponen.
It isn't the first swine flu-related security warning issued in recent weeks, after a specially created PDF file containing malware was spotted.
Earlier this week, the Flu Survey website, which asks sufferers of swine flu to complete a short survey in order to help track the spread of the disease, was launched.
