August 23rd Sophos Update Causes: 32-bit Outlook 2013, Internet Explorer, FireFox to not open in Windows 10

The subject sums it up.  Since yesterday's update, we noticing a consistent trend in our environment.  Computers running Windows 10 are having issues opening Outlook 2013, IE and FF to not open after a Sophos update yesterday morning around 10:30 AM (EST.)

In the event viewer, checked why the applications are failing to open and it shows APPHANG, faulting module: C:\Program Files (x86)\Sophos\Sophos Anti-Virus\sophos_detoured.dll

 

The work-around has been to cut/paste both sophos_detoured.dll and sophos_detoured_x64.dll out of that folder. As soon as we do that the applications launch.  This only started happening August 23rd morning.

 

Anyone have experience with this so far?  I would have expected to see this on the forums already.

 

Thanks,

  • Sorry for the delay -- found my on prem testbed was badly out of date.

     

    Running same version as you on W10 test vm, no crashes anywhere.  This has Office 2016 on it, but IE / Edge / Firefox all work fine.. as does office.

     

    You probably have some other piece of software on there that in concert with the new update is causing this issues.  You may want to pre-emptively send Sophos Support a SDU package.

  • Thanks for testing on your environment.  I will try removing our other 'standard' software one by one and see if that resolves this issue.

     

    Is your Windows 10 test VM running the latest Office/IE patches?

  • Yes.  Like I said one difference it is running Office 2016 not 2013.  But firefox works OK (you mentioned that was broken too).
