Google says last year it eliminated 780 million "plain bad" ads carrying malware, promoting fake goods or leading to phishing sites.
Ad networks have become a popular mechanism for distributing malware, such as the malvertising campaign spread via Google's AdSense at the beginning of last year.
To prevent bad ads from harming internet users and threatening Google's multi-billion dollar ad empire, Google ads and commerce SVP Sridhar Ramaswamy says the company has now hired more than 1,000 people across the globe whose sole purpose is "fighting bad ads".
It seems that a lot of effort is put towards fighting malvertising, but it seems that this is still not enough. Maybe in the future, a fully automatic prevention and solution system will be implemented to take care of these, but right now, it's good to see that some people try to take things in their hands and fight off malvertising using the resources they have.
