Google recently released its Q2 2010 report of spam and virus trends, drawn from data collected by the company's Postini email security services.

"Spam and virus volumes this year have continued their upward trend," wrote Google's Adam Hollman and Gopal Shah. "Q2'10 has seen a sharp 16% increase in spam volume over Q1'10. Virus traffic has moderately increased 3% increase this quarter, however Q2'10 virus was 260% higher than Q2'09. These trends tell us that the spammers are still extremely active, and their botnets produce high levels of spam and virus traffic."
