Imac crashes every time i run a scan
« on: July 03, 2011, 08:46:57 PM »
twice now I have run a scan and walked away from the PC to come back finding that it had crashed.
Both times, I ran a full system scan and use the PC for some time while the scan was running.  Both times, when I rebooted, there was no log in avast for the scan I was running. 

The first time I started the scan at 1:16 am and went to bed about an hour later with it still scanning.  When I woke up, the screen saver was frozen and the clock was frozen on 3:48 am.  I had to reboot. Since this would have been significantly after the screensaver kicked in, I thought the crash might have happened if the mac tried to put the hard drive to sleep or something (although it shouldn't have if avast was still running a scan) so I turned off that setting and ran another scan.

The second scan, I started around 10:30 and left the PC around 10:45.  When I got home at 1:40, there was a screen saying that I needed to reboot my machine.  I did so.  After I rebooted, it popped up the "you shut your computer down because of a problem" dialog.  I opened details and got this:

I have not had this type of issue before.  In fact, I think I have had one or two crashes in the entire 4 year life of the mac (other than these 2) and the system is almost always on.

System Specs:
I am running OSX version 10.6.5 on an iMac8,1 with an Intel Core 2 Duo 2.8 GHz processor.  I have one bootcamp/windows partition installed.

hippyhillary,

we were so far unable to reproduce the crash. We will continue trying to do so, but in the mean time it would be very helpful if you could kindly follow instructions below. It could point us to the source of the issue:

(1) Disable Filesystem Shield:
 -- In the main GUI go to SHIELDS >> File System Shield, unlock the lock on the bottom of the window and move the slider to the OFF position).
 -- [OPTIONAL] Enter the following command in Terminal (note this step requires administrative rights):
    sudo kextunload  "/Library/Application Support/Avast/AvastFileShield.kext"
    (It would be better if you do this, but feel free to skip this if you really are not familiar with command line at all.)

Then run the Full System Scan and report if it keeps crashing.

(2) If still crashing, then please also disable sleep of the Mac in System Preferences and run the Full System Scan once again and report if still crashing.

Thanks
Mity

It would be also helpful if you can provide the following log files:

/var/log/daemon.log
/var/log/fileshield.log
/var/log/kernel.log
/var/log/system.log

Note they can be quite big (the beta is logging quite a log), so consider compressing them before uploading. You can upload to ftp://ftp.avast.com (login as "anonymous", password is any e-mail address), go to "incoming" folder and upload there. (Please note that 'anonymous' cannot see what the folder contains but can upload anyway).
