Microsoft AV Flags Google.com as ‘Blacole’ Malware
Summary: A faulty Microsoft security update shipped on Valentine's Day 2012 caused Microsoft Security Essentials and Forefront to flag google.com as Exploit:JS/Blacole.BW, a Blackhole Exploit Kit threat, with Internet Explorer raising the alarm when users visited the site. Microsoft confirmed the false positive and corrected it in definition update 1.119.1986.0 or higher, and the alert's default 'remove' action reported it could not find the threat.
What's compelling: A single bad definition pushed to Microsoft's antivirus users flagged the world's most-visited website as malicious, and one commenter reported blocking the entire google.com domain at his firewall in response - a reminder that a false positive in your endpoint tooling can trigger your own people to cut off critical services.
