Two weeks ago we switched our corporate email to Malwarebytes. Starting the middle of last week we have had a steady increase in the number of users that can't print from Adobe or Office, Adobe files will crash out if you try to print. IE and/or Office will randomly hang and then close.
the application log is tracking this every time it occurs. The error we get is App Hang (then the app name) followed by EF472831.dll
I have not been able to find out what EF472831.dll does, but it is the file causing the error every time. I have tried to re-register the dll but that doesn't work either.
So far uninstalling Malwarebytes appears to make Office more stable, but has no affect on Adobe. I am currently running a system restore on one of the affected users prior to the Malwarebytes installation to determine if that will solve the problem.
I have also sent a support ticket into Malwarebytes. Any ides on this would be appreciated? The list of affected users is slowly growing. And every affected user has the exact same EF472831.dll error message logged.
