WARNING! Sophos AV for Mac - TURN IT OFF!

[mefoster]

Do not download or activate the Sophos IDE file that was released today at around 4pm. It contains an error which is misidentifying lots of binary files as being infected with the OSX/Inqtana-B (a variant of the Inqtana.A Bluetooth worm). The files are almost certainly not infected with this worm (which is, in fact, pretty lame and only attempts to exploit a hole that was fixed nearly a year ago). This is a bug in Sophos AV, not an outbreak of a worm.

If you let Sophos run with Intercheck enabled and using this IDE file, Sophos *will* trash your Mac.

Still, it's nice to know that Anti-Virus software is "protecting" your machine eh?
