A new research report from online security experts has found the Rustock spambot continues to spew annoying and potentially dangerous messages to many unsuspecting users.
The research, which accumulated data for six months, found the prevalence of the spam peaked at 60 percent and never fell below 20 percent during that period.

Campus Technology recently reported that Rustock spam accounts for 43 percent of all spam messages, followed by Mega-D, which generates only 10 percent.
