Network Associates have reported on an internet worm previously thought to be of little harm, that appears to be spreading and has already reached some companies within the UK. They also reported that if affected that more action is required than simply downloading the antivirus update.

Look out for a christmas card titled Navidad. Users will become infected if they open the attachment entitled Navidad.exe. This is an internet worm that originated from South America that will attach itself to addresses in the user's in-box, not the address box which is what the Love Bug did.

If this file runs, it will display an error message - UI, a blue eye icon that will appear in the system tray next to the clock in the lower right corner of your screen. A copy of this is then saved to the file 'winsvrc.vxd' in the windows directory.

It will not delete files like the Love Bug virus, however it will scare some users. System Administrators will need to go to the infected machine and manually remove it.
