Symantec Security Response encourages you to ignore any messages regarding this hoax. It is harmless and is intended only to cause unwarranted concern.
Type: Hoax
This is a hoax that, like the SULFNBK.EXE Warning hoax, tries to persuade you to delete a legitimate Windows file from your computer. The file that the hoax refers to, Jdbgmgr.exe, is the Microsoft Debugger Registrar for Java. It may be installed when you install Windows.
NOTE: Recent version of this hoax take advantage of the recent outbreak of the W32.bugbear@mm worm, and the fact that the Jdbgmgr.exe file that is mentioned in the hoax has a bear icon. The actual W32.bugbear@mm worm file is an .exe file and does not have a bear icon.
The Windows Jdbgmgr.exe file has a teddy bear icon as described in the hoax:
CAUTION: Jdbgmgr.exe, like any file, can become infected by a virus. One virus in particular, W32.Efortune.31384@mm, targets this file. Norton AntiVirus has provided protection against W32.Efortune.31384@mm since May 11, 2001.
NOTE: If you have already deleted the Jdbgmgr.exe file, in most cases, you do not have to reinstall it. The following is quoted from the Microsoft Knowledge Base article Virus Hoax: Microsoft Debugger Registrar for Java (Jdbgmgr.exe) Is Not a Virus (Q322993):
"The Microsoft Debugger Registrar for Java (Jdbgmgr.exe) is only used by Microsoft Visual J++ 1.1 developers.
