Sophos fixes false positive in OSX/Inqtana-B detection

Sophos Press Release

Sophos customers automatically updated to fix problem

SophosLabs™, Sophos's global network of virus, spyware and spam analysis centers, issued an update at 14:43 GMT on Tuesday 21 February to detect the OSX/Inqtana-B worm for Mac OS X.

Unfortunately, this update was flawed, and Mac OS X users may have been mistakenly warned by Sophos Anti-Virus for Mac OS X that some files on their computers were infected with the worm.

SophosLabs quickly discovered the problem, and issued a revised update less than two hours later at 16:40 GMT, Tuesday 21 February. Customers who take advantage of Sophos's automated updating facility will have been automatically updated from this time, and will no longer experience the false positive.

Additionally, an email was sent to customers who are subscribed to Sophos's email notification list informing them that the IDE had been updated to correct the detection issue.

Sophos apologizes for any inconvenience that this problem has caused. Measures have been put in place to ensure that the problem does not occur again. Any customers who require further guidance are recommended to contact Sophos Technical Support.

Sophos would like to remind customers that the OSX/Inqtana-B worm is not in-the-wild, and is unlikely to be encountered.
