Google is warning its users about an adware campaign that has infected some ads and hijacked their behavior.
The malware was detected by Google and it’s not known how long it has been active.
Google said it’s testing the malware to see if it can be removed.
The adware is spreading like wildfire among some people, who have become accustomed to Google’s free browsing.
The ads were downloaded over the Internet and used to help people find other websites.
Some users have reported getting infected after opening an email from Google that contained a link to an ad.
Google says it can’t stop the ads from being downloaded, but it can block access to the adware’s servers.
