Romanian antivirus firm, BitDefender, claims to have discovered malicious code in Google's AdSense service. Google has been swift to respond:
Google said on Wednesday: "We have canceled customer accounts that display ads redirecting users to malicious sites or that advertise a product violating our software principles."
"We actively work to detect and remove sites that serve malware in both our ad network and in our search results. We have manual and automated processes in place to detect and enforce these policies."
Being proactive against malware is an uphill battle to be sure, and Google certainly has their work cut out for them.
