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. Microsoft acknowledged the gaffe, and said approximately 3,000 users were affected. Chrome was fingered as Zbot, better known as Zeus, a widespread botnet Trojan that focuses on stealing online banking credentials. Microsoft told users to update Security Essentials with the new definition file, then reinstall Chrome. Chrome bookmarks were not restored after reinstalling the browser.”]
