Visitors to Yahoo’s Web pages who viewed ads the past few days are potentially at risk of having their computers infected by malware, according to published reports Sunday.
Fox IT — an Internet security firm that discovered the alleged malware infection — says 300,000 users were visiting the infected ads every hour. That means roughly 27,000 computers and devices were being infected every hour since typically 9% of computers are actually infected after visiting the site. Most computer users either use software that combats such infections or may have configured their computers to be resistant to the attacks.
