I've just received (but intercepted) a variant of the HYBRIS virus - Hybris Virus at Symantec.It came to me in an email with no subject or sender information, and an attachment GHHHBBGH.EXE of approx 22k in size.
It has been quarantined for dissection - heh, heh, heh!!
I've no idea from whence it came - so be warned!
