Conficker is a widespread worm targeting the Microsoft Windows operating system. To date, there are five variants of the worm.
GFI LanGuard 9 and later, using the latest security updates, is able to detect machines which are infected with the Conficker worm. Infected machines show a High-Security Vulnerability indicating that Conficer worm infection has been detected on the machine.
GFI LanGuard also reports machines which do not have Microsoft security update MS08-067 installed. Security update MS08-067 targets a vulnerability used by Conficker to propagate itself. Thus, machines which do not have MS08-067 are at risk of being infected.
Apart from detecting and reporting infected machines or machines which are at risk of infection, GFI LanGuard also supports the deployment of MS08-067 on machines which are still missing the security update.
NOTE: A variant of the Conficker worm imitates the installation of security update MS08-067. GFI LANguard is still able to perform correct detection of the missing security update and report that the machine is infected accordingly.
