Antivirus firm secures lists after virus leak

Finland-based F-Secure has added more security to its customer mailing lists, after a moderator accidentally forwarded a virus to users of the company's antivirus software. The moderator for the company's U.K. customer list on Feb. 26 forwarded an e-mail generated by the virus NetSky.B. As a result, the company will no longer accept outside e-mail messages to its list, and attachments will be blocked, said Mikko Hypponen, director of antivirus research for the company.

"We have taken several steps after (the incident) to make sure it will never happen again," he said.

The virus e-mail had been sent to the antivirus list's moderator after a PC in the United States--with no association to F-Secure--became infected. The address for the list happened to be on the computer. When the moderator received the e-mail, he accidentally gave permission for the software to forward the message to subscribers.
