Several recent Google Chrome updates have been flagged as potentially dangerous by Microsoft’s built-in antivirus and endpoint protection service, according to reports.
A number of Windows system administration reports have shown that Microsoft Defender for Endpoint has marked browser updates delivered through the Google Update service as suspicious.
The activity is thought to be due to a false positive, but it’s another possible headache for Microsoft and Google as they try to get their products out to as wide an audience as possible.
Windows reports, seen by BeepComputershow that affected users have received an alert about a possible “multi-stage incident involving execution and defense evasion”.
However, Microsoft claims to have investigated the issue and found that it was a false alert caused not by criminal activity, but by a conflict of alerts.
“Admins may receive a false positive alert for Google Update on Microsoft Defender for Monitored Devices,” Microsoft said. The company later revealed that it fixed the issue after about an hour and a half, with customers now able to fully utilize Microsoft Defender for Endpoint again.
The news is the second such incident involving Microsoft Defender and false positive alerts in recent months.
In March 2022, a similar incident saw certain Microsoft Office updates flagged as ransomware threats by Defender for Endpoint. Microsoft was quick to investigate the issue, again confirming that it was a false alarm.
In early December 2021, Defender also blocked users from opening certain Office files and launching various applications, triggering false positives related to the Emotet malware.
Several serious security issues have plagued Google Chrome in recent months, including a string of zero days. Most recently, the company released Chrome 99.0.4844.84 for Windows, Mac, and Linux to fix a high-severity zero-day vulnerability that allows remote code execution.
Zero-day threats have become a top concern for businesses and end users, with Google’s internal security team recently noting that the number of issues hit an all-time high in 2021.
