“Q3’10 spam and virus trends confirm that spammers are still hard at work distributing malicious content in new and creative ways. August saw a massive 241% increase in virus volume over July, representing the greatest recorded surge in viral activity since 2008. Overall, payload virus volume increased 42% over Q2’10 and 10% over Q3’09, while spam levels decreased 16% and 24% over same periods, respectively.
