New JPEG virus released Dec-08-2006

Users of Internet Explorer are vulnerable and the first versions are being distributed through adult news group pictures.

To see if you have been infected by this virus, look for a directory
named c:\windows\system32\system\ that has nvsvc.exe and winrun.exe in it.

On 14 September, Microsoft released Security Bulletin MS04-028, which warned that because of a problem with the way that Windows handles JPEG image files, malicious code could be executed on a user's machine if they simply viewed an ordinary image file. Because Microsoft's Internet Explorer browser is vulnerable, users could be attacked just by visiting a website that has affected images.

The virus is a Trojan, which makes the computer available to the hacker as a drone or "zombie," which means that it could be used to forward spam onto other users, or to bombard websites in a distributed denial of service (DDoS). The virus is also able to access information on the user's computer, including software license keys, credit card details or other confidential information. If the computer is on a network, then the virus will have access to all of the shared drives and could spread throughout the LAN.

Some information on the first discovery of the virus can be found at EasyNews

Users of any Microsoft OS are encouraged to run Windows update to prevent infection of their PC.
Users of infected PC's should consult their anti virus makers web site for updates and removal tools.
