A2service.exe Not Terminating Properly At System Shutdown

Recommended Posts

I happened to be reviewing my reliability history in Win 7 and noticed that a2service.exe is not terminating properly at system shutdown time. This started on July 8 and has continued since that time. Also explains the delay I have been noticing at shutdown time. Also appears that this might be affecting other things since I had issues this morning at boot time with some apps working properly; IE11 and Win disk cleanup would not startup. A subsequent reboot corrected those issues.

 

Note that the a2service.exe issue only occurs at system shutdown but not at system restart?

I am attaching the dump files minus the full dump file since it is to large from the reliability monitor analysis.

 

There is also something very odd. Yesterday when I examined .dll usage by a2service.exe, I noticed an unsigned OpenSLL .dll loaded. Below is extracted from one of the reliability monitor dump files. Today, I do not see that .dll loaded by a2service.exe. Why is a OpenSLL file that appears to date to 2005 and unsigned being loaded into a2service.exe?

-EDIT- Will also add that there is a specific ver. of ssleay32.dll written for AMD64 processor which is what I use.
