Avast and Mountain Lion kernel panic
« on: July 28, 2012, 10:06:25 PM »

I've encountered a big issue with avast 7,  since I've upgraded my 2012 macbook air from lion to mountain lion.
I.e., sometimes when I shut down the pc, the screen freezes for some seconds and then I get a kernel panic.  :-\

I have all the updates installed, and even tried to fresh install mountain lion but the problem is still there.

Kernel panic happens only SOMETIMES. I noticed, instead, that (only with avast installed) on shutdown i get a "freezed and dimmed" desktop instead of the grey screen which I could see for 1-2 seconds.

I hope someone could help me.
Thanks in advance

Are there any interesting entries in the kernel log (/var/log/kernel.log)?

I had the same thing happen after I upgraded to Mountain Lion.  OS X (correctly!) flagged Avast as incompatible software and I (foolishly) ran the application, which then seemed OK.  But there was a kernel panic when I shut down sometime later.

I've now uninstalled Avast and will wait a few weeks before installing it again.

Can you please provide a kernel panic report log? You should find it in the directory /Library/Logs/PanicReporter
