Yes it's a hoax, this is taken from the Nortons Anti Virus site. If you ever recieve something similar go to this site and have a read.
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 a Java Debugger Manager. It is a Microsoft file that is installed when you install Windows.
It 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, some Java applets may not run correctly. This is not a critical system file. The file version may vary with your operating system and version of Internet Explorer. If you want to restore the file, please contact Microsoft for instructions.
