DAT 8630 was published at 1.45PM PST on October 20, 2011 and contained within it a faulty signature for OSX/Flashback.C. A MAC OSX file format was mistakenly matched as a Malware component resulting in multiple files being renamed or quarantined depending upon the policy settings. The resulting impact is a potentially unbootable system. DAT 8632 has been published at 4:30AM PST on October 21, 2011 to remedy the faulty signature. In the event that your system did not update to DAT 8630 or did not report a detection for OSX/Flashback.C you will not be impacted by this false positive. Update: Remediation scripts and additional recovery logic is available via our Support department. Please contact your Support representative for further assistance.
