I recently tried to manually update one of my managed users to the latest version of Avast. The update appeared to work properly, but a subsequent reboot brought up the following popup error message (immediately after logging in):
Popup Error Message:
Entry Point Not Found : The procedure entry point cmnbInitExt could not be located in the dynamic link library aswCmnB.dll.
The following Avast services will not start:
“C:\Program Files\Alwil Software\Avast4\aswServ.exe” (Automatic)
“C:\Program Files\Alwil Software\Avast4\aswUpdSv.exe” (Automatic)
“C:\Program Files\Alwil Software\Avast4\aswMaiSv.exe” /service (Manual)
“C:\Program Files\Alwil Software\Avast4\AvAgent.exe” /ServiceStart (Automatic)
I tried a Repair install (from Add/Remove Programs), but that failed with the following error: “There was an error while changing the product configuration.” So, I uninstalled Avast, rebooted, reinstalled Avast, rebooted, and everything started working (older Avast program version).
So, once again, I ran a manual program update (by right-clicking on the blue ball), and rebooted. The same error returned. Yet again, the Repair install failed. I found a similar topic here: http://forum.avast.com/index.php?topic=19094.0, so I also searched for the file aswCmnB.dll. I only found one instance, in the Avast program folder.

Today, a second user began experiencing this problem. Any suggestions would be greatly appreciated, thanks!
