A new email virus hoax is making the rounds. It will warn you that there is a new virus that is undetectable by Norton or Mcafee. (it's NOT a virus so of course they can't detect it!) It then tells you to delete the file "jdbgmgr.exe ".
DO NOT DELETE THIS FILE!!!!!

Here is a link to the Norton site with a full explanation:

Jdbgmgr.exe file hoax (http://www.symantec.com/avcenter/venc/data/jdbgmgr.exe.file.hoax.html)

Hope this saves you some trouble.
