Here's some more information, with the real sources of the virus. It doesn't come from someone looking at the BB but from someone who doesn't have anti-virus software, who gets it and sends it out to us.

In simple terms, the infected person is the problem, not the BB.

The only way to never get a virus sent to you is never log onto the internet, have no friends and get no email.

And now for the details... The worm loads Windows Address Book into memory, reads .NET Messenger data, Yahoo! Messenger profiles, ICQ data files, HTML, DOC and TXT files in cache folders, desktop and personal folders and stores e-mail addresses it could find there into a DLL file with a random name in Windows folder.

Translation, it searches many places on the infected computer for email addresses. (NOT FROM WEB BBS) This one also, fakes/spoofs the senders address.
