Kaspersky Labs, a leading international data-security software developer, reports the detection of the Internet-worm known as I-Worm.Zircon.c. At this time it is known that infections from this dangerous virus have occurred in several countries.
The worm is activated only if a user launches this program file. Zircon.c is a worm that activates only once - it does not install itself into the system and does not repeatedly launch itself (except in cases where a user repeatedly opens the infected attachment).
If the worm is launched, it sends itself to all the users in the Outlook address book by using the SMTP server, which it automatically connects with and manages.
The defense procedure against "Zircon.c" has already been added to KasperskyT Anti-Virus database.
Further details regarding this Internet-worm are available in the Kaspersky Lab Virus Encyclopedia.
