Information about the JDBGMGR.EXE virus hoax.

Published Apr 22, 2002


Virus name:   JDBGMGR.EXE.

Status:   Hoax.

Example:   [Collected on the Internet, 2002]



I got this message about a virus that can produce lot of dammage [sic] to your computer. If you follow the instructions which are very easy, you would be able to "clean" your computer.


Apparently the virus spreads through the adresses book . I got it, then may be I passed it to you too, sorry.

The name of the virus is jdbgmgr.exe and is transmitted automatically through the Messanger and addresses book of the OUTLOOK. The virus is neither detected by Norton nor by Mc Afee. It remains in lethargy ("sleeping") for 14 days and even more, before it destroys the whole system. It can be eliminated during this period.

The steps for the elimination of the virus are the following:

1. go to START and click FIND

2. in "FILES andFOLDERS" write: jdbgmgr.exe

3. be sure that it searches in "C"

4. click SEARCH NOW

5. if the virus appears (with icon of a small bear) and the name"jdbgmgr.exe" . don't open it !!! in any case !!!

6. click the right button of the mouse and destroy it

7. emty the recyclage bin

If you find the virus in your computer please send this mail to all the people in your addresses book .



Origins:   Like the SULFNBK.EXE hoax, this bogus virus warning (also known as the "Bear Virus") attempts to lure gullible users into deleting perfectly innocuous, standard Windows files from their systems.



this case the target file is JDBGMGR.EXE, a Java Debug Manager program used by the Microsoft Java runtime engine. This file is included as part of a standard Windows installation and is not a "virus." (The icon for this file is a graphic of a bear like the one shown to the right.)

If you deleted this file, don't sweat it — JDBGMGR.EXE is only important to programmers who use Microsoft Visual J++ 1.1 to develop Java programs. Its absence will not cause your PC to stop working or interfere with your applications, so if you're not a Java developer, you don't have to worry about restoring it. Consider the experience a lesson learned about the perils of believing and acting upon unverified e-mail warnings.

Windows 2000 and Windows ME include a Windows File Protection (WFP) feature that will recover shared files such as JDBGMGR.EXE if they are overwritten or deleted. Users of other Windows operating systems can only retrieve JDBGMGR.EXE by reinstalling the Microsoft Virtual Machine (VM) component, but Microsoft is no longer offering it as a download.
