What caused global shutdown of PCs in 2010 & how is it linked to CrowdStrike's Kurtz?

In April 2010, Windows XP computers crashed worldwide after McAfee released a faulty antivirus update. It was meant to destroy the 'W32/wecorl.a' virus, but it incorrectly identified a critical 'svchost.exe' file as malware and relocated it. This caused systems to crash and reboot repeatedly. CrowdStrike CEO George Kurtz was McAfee's Chief Technology Officer when the buggy update was released.
