Microsoft Defender Advanced Threat Protection (ATP), the commercial version of the ubiquitous Defender antivirus and Microsoft’s top enterprise security solution, is currently having a bad day and labeling yesterday’s Google Chrome browser update as a backdoor trojan.
The detections, as can be seen in a screenshot above shared with ZDNet by one of our readers, are for Google Chrome 88.0.4324.146, the latest version of the Chrome browser, which Google released last night.
As per the screenshot above, but also based on reports shared on Twitter by other dismayed system administrators, Defender ATP is currently detecting multiple files part of the Chrome v88.0.4324.146 update package as containing a generic backdoor trojan named “PHP/Funvalget.A.”
