|Microsoft scrambled earlier today to revise an antivirus definition file that deleted Google's Chrome browser from users' PCs.|
"Wow, that's certainly one way to win the browser war," said Andrew Storms, director of security operations at nCircle Security.
Microsoft issued a corrected definition file around 10 a.m. PT Friday, about three hours after users began reporting the false positive on Google's support forum.
"An incorrect detection for PWS:Win32/Zbot was identified and as a result, Google Chrome was inadvertently blocked and in some cases removed from customers PCs," Microsoft said in a statement posted to the Facebook page of its malware research center. "We have already fixed the issue..., but approximately 3,000 customers were impacted."
