(3/19/2004) In May 2001, a virus warning began circulating, urging people to search for and delete a file called sulfnbk.exe because it supposedly contained an uncurable time-released virus. Many people continue to fall for the hoax, and this variation is nabbing even more.

Subj: sorry guys about this virus!
I believe that I was sent a virus. It sends it on to everyone in your address book, so everyone check your computer! I am so sorry! It is easy to get rid of though so get it off your computer.
Here's how to get rid of it.
1. Go to Start--Find--Files or Folders
2. Under Named, type jdbgmgr.exe and click Find Now. Make sure you are looking under Drive C. DO NOT CLICK ON IT IF IT APPEARS!!!
3. If the virus appears , the icon next to it will be a small teddy bear and the name will be jdbgmgr.exe.
4. DO NOT OPEN IT Just right click on it and DELETE it, it will be sent to the recycle bin.
5. After you see it disappear, go to the recycle bin and delete it from there as well. If at all possible, empty the recycle bin under file.
If you find this virus in your system, please sen this message to every onw in your address list asap before it causes any damage.

If you do a search on virtually any Windows system, you will probably find jdbgmgr.exe. It is the Microsoft Debugger for Java. As with all executable program files, it can become infected by a virus, but its mere presence does not necessarily indicate an infection. Deleting the file will not protect you from some time-activated virus and could cause your computer to do weird things. You should only be concerned if you find the file in any folder other than c:\windows\system
If you were one of the unfortunate many who deleted the file before learning the truth, you can rest easy knowing that, unless you frequently develop programs in Microsoft Visual J++ 1.1, you don't need the file. If you use Windows ME or 2000, the system protection features of those operating systems will automatically restore the file the next time you start your computer. Unfortunately, ongoing legal wranglings between Microsoft and Sun Microsystems over the Java engine mean that fixes aren't available for older versions of Windows.
Not unexpectedly, this one has mutated as it circulates, and a newer version actually instructs you to not only delete the suspect file, but also the entire contents of the folder that houses it.

URGENT VIRUS WARNING
PLEASE CHECK YOUR COMPUTER FOR THIS ONE I FOUND IT IN MINE ( ##Name of Sender Inserted Here##)
A virus has been passed on to me by an unknown contact. My address book in turn has been infected. Since you are in my address book there is a chance that you will find it in your computer too. I followed the instructions below and eradicated the virus easily. Note that the virus (called jdbgmgr.exe) is not detected by Norton or Mc Afee anti-virus systems. This virus sits quietly for 14 days before damaging the system. Messenger and the Address book send it automatically, whether or not you send e-mails to your contacts. Here's how to check for the virus and how to get rid of it.
1. Go to Start, Find or Search option.
2. In the file/folder option, type the name, jdbgmgr.exe
3. Be sure you search you C drive and all sub-folders and any
other drives you may have.
4. Click: "Find now"
5. The virus has a grey teddy bear icon with the name jdbgmgr.exe
DO NOT OPEN IT!!!
6. Go to edit (on the menu bar) and choose SELECT ALL to
highlight the file without opening it.
7. Now go to File (on the menu bar) and select DELETE. It will
then go to the recycle bin.
8. Go to the recycle bin and delete it there as well.
9. If you found the virus, you must now contact all the people in
your address book, so they can eradicate it in their own address books.
TO DO THIS:
1. Open a new email message
2. Click the icon of the address book next to the "To" (it is the little open book)
3. Highlight each name in turn and add it to "BCC"
4. Copy this message, enter subject and paste to email and send.
Sorry for any inconvenience.

Versions surfacing in Spring 2004 shortened the offending file name to jdbg.exe, jdbgm and other variants.
Most virus warning e-mails are false, or contain incorrect and misleading information and rarely offer helpful instructions for preventing/removing infection. As in the case above, the advice given does enough damage on its own. Anti-virus software is inexpensive, readily available and provides real piece of mind. When a new virus is found in the wild, the major anti-virus manufacturers have updates that detect it available within hours. Get some, keep it updated and never forward another virus warning.
