"The online-advertising industry is scrambling to quell a long-standing  problem that has taken a turn for the worse: the spread of malicious ads  on the Internet's top commercial websites.
Several new twists have made so-called  malvertisements a fast-rising threat to consumers — and a big headache  for publishers, advertisers and ad networks, say technologists and  security researchers.
The spread of infected  online ads has spiked tenfold over the past year, according to research  disclosed by security intelligence firm RiskIQ at a recent Online Trust  Alliance conference in Washington, D.C.
RiskIQ  documented a peak of 14,694 occurences of malvertisements in May of  this year, up from 1,533 in May 2010. Each corrupted ad could have  infected the PCs of thousands or millions of website visitors, based on  how long the ad ran, says Elias Manousos, CEO of RiskIQ."
