An obscure messaging feature in Windows could be the latest source of security problems for Internet users, experts have warned
Security experts are warning users to switch off a Windows messaging feature that has been taken over by spammers and could now pose the latest security threat for Windows users.
The feature, known as the messenger service, was originally designed to let a network administrator send warnings to users when, for example, a server is scheduled to go down for maintenance. Last year, bulk advertisers began using the tool to send pop-up advertising messages directly to a user's computer, and researchers say it would be simple for a virus writer to exploit the feature as well. The feature is not related to Microsoft's instant messaging software.
