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 hoax, like the SULFNBK.EXE Warning hoax, tries to encourage you to delete a legitimate Windows file from your computer. Jdbgmgr.exe is the file to which the hoax refers, and it is the Microsoft Debugger Registrar for Java. The Jdbgmgr.exe file may be installed when you install Windows.
NOTE: Recent versions of this hoax take advantage of the recent outbreak of the W32.bugbear@mm worm. The Jdbgmgr.exe file mentioned in the hoax has a bear icon. The actual W32.bugbear@mm worm file is a .exe file and does not have a bear icon.
The Windows Jdbgmgr.exe file has a teddy bear icon in the hoax, as illustrated below:
CAUTION: A virus can infect Jdbgmgr.exe. The W32.Efortune.31384@mm virus, in particular, 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 need to re-install it. The following quote is extracted 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.
If you follow the e-mail message instructions and delete this file, you do not have to recover it unless you use Microsoft Visual J++ 1.1 to develop Java programs on Windows XP, Windows NT 4.0, Windows 98 Second Edition, Windows 98, or Windows 95."
If you need to restore this file, follow the instructions in "Virus Hoax: Microsoft Debugger Registrar for Java (Jdbgmgr.exe) Is Not a Virus (Q322993)."
