This is a very destructive worm which will wipe your hard drive out if your computer gets infected with it. As usually, don't download files you are not absolutely sure are free of Viruses/Worms/Trojans. Update your antivirus software regularly.
Information from Juergen Amling, the webmaster of the Imperial St. Landry Genealogical & Historical Society web site
I'm are sure you are aware that there are so many computer viruses going around, but then there are also almost as many hoaxes spreading warnings about viruses that don't exist and some of these hoaxes want you to delete files that's needed for the operation of your computer. It is almost impossible to sort thru all these messages. I will try to give you updated information on this page, but can give you no guaranties and don't assume any liability.
Please beware of one thing: don't download any attachments to e-mails unless you are absolutely positively sure that this attachment is sent to you by somebody you know and that he/she knows it's sent to you. I would suggest to delete any e-mail with their attachments if they have just a generic addressing, like: Hi, or You need to see this, Please check this out etc. I do not consider it a legitimate e-mail if it doesn't have my name in the salutation but only one of the mentioned words. If you use Outlook or Outlook Express turn off the preview pan, that means that it will show part of the e-mail if you only click on it once. To disable the preview, you go to View, then Layout and then un-check the show preview pan option. In the future I will have more information but right now here are two very good sites with information about viruses and hoaxes:
Symantec and McAffee
Both sites are from companies selling antivirus software and they have a lot of information. You do need an antivirus software. They basically all good, but when you install them, you have to keep up with what they call signature files or updates. These files contain information about the newest viruses, and if you don't update the information the antivirus software can not detect the newest viruses and it will not help you.
* Everybody using Windows XP needs to go to this site: Windows XP Vulnerability
* I get a lot questions e-mails warning about a file sulfnbk.exe. These warnings allege that this file contains a virus and needs to be deleted and that no antivirus software can find it. These messages are hoaxes. This file is used by the windows operating system to restore long file names. It's not crucial for everyday operation, but should not be deleted. If you did delete it and want to restore it this site from Symantec will give you instructions about how to do it.
