No, you shouldn't send it to everyone you know. Before forwarding along any virus announcement, you should seriously consider the validity of the message, as the overwhelming majority of such announcements, such as the one about jdbgmgr.exe, are hoaxes.
Real virus warnings do not use all capital letters. They do not try to scare you. They do not tell you to forward the message to everyone you know. They do not mention press releases from big companies that have nothing to do with virus announcements or antivirus software (i.e., Microsoft, AOL, IBM, Intel). They do not make references to other articles without citing them appropriately.
Real virus announcements do give official virus names and URLs (web pages) that you can go to for more information. They provide the date that the virus was identified and may include fixes. Most importantly, real virus announcements state clearly who is issuing the announcement.
You can find out if a virus is real or not by searching for the subject line or any of the text using a search engine, such as http://www.google.com.
