Sophos preventing OS X from shutting down gracefully?

KittenRainbow

Hello Guys

I have a problem with some OS X Computers. About two months ago, we did a clean install of OS X 10.10 Yosemite on about 40 MacPros.
Together with the new install we also installed sophos antivirus for mac (we did so by installing it in the master image and then cloning the master image onto all computers).

Since then, some users complain, that their computers are "incredibly" slow (whatever that means, couldn't see it with my own eyes) and, the bigger problem is (which I actually witnessed) is, that some computers don't shut down nicely (they hang on the shutdown screen and hang there forever, over 12 hours! You then need to force shutdown).

I trained the users to send me photos from the output of the verbose shutdown whenever a problem occured and on every single photo I received, there is an error of sophos (I attached the photos).

Could you tell me if you know this problem and if yes, what you did to solve it?
I already did all those dtandard Mac-tricks (resetting of PRAM and SMC, permission repair and even ran cocktail, updated and reinstalled the OS X patches) without any effect.

    I don't know if this is relevant, but in the Windows world, one never clones an image with anti-virus software. AV is applied only after the sysprepped machine is made unique - and then the AV is unique as well. Whether this is also the case in the Mac world, I do not know. However, you could test my theory to see if it improves performance. I have about 10% macs in our environment.
