Microsoft's anti-malware software has mistakenly classified Google's Chrome web browser as a 'Severe' banking Trojan.
According to The Register, "On Friday, a faulty signature update for both Microsoft Security Essentials and Microsoft Forefront incorrectly detected the Chrome executable file for Windows as a component of the notorious ZeuS trojan."
While it seems that so far both Google and Microsoft are saying little about the alleged incident, there is an interesting note at the top of Microsoft's Malware Protection Center's Threat Research and Response Encyclopedia:
"NOTICE: September 30, 2011: MMPC has identified an incorrect detection for PWS:Win32/Zbot affecting Google Chrome. Signature version 1.113.672.0 or higher addresses the issue."
Update: 03/10/2011 11:22 Both Microsoft and Google have acknowledged the situation [The Register].
