If you mean a sysmsgr.exe from OfficeCyberAlert, then it's legit.

But if you mean the display name like below pointing to sysmsgr.exe? then it's a bad file.
[System Messenger Service] sysmsgr.exe

Rightclick on the file and look at the properties and see if it has a company name.
Where is the file located?
Instead of sysmsgr.exe did you perhaps mean sysmgr.exe ?
Assuming for the moment you did, here's information on sysmgr.exe :

As stated, some Malware camouflage themselves as sysmgr.exe.   You could check to see if your file is located in c:\windows or the c:\windows\system32 folder.

Whichever file you meant, and just to be sure, have you tried scanning for Malware with Malwarebytes?
If no, try downloading & updating Malwarebytes anti-Malware, from here:
Run in normal mode.

Another option is to download & run Process Explorer v12.04 to see if running OfficeCyberAlert (and sysmsgr.exe) is causing high CPU usage.  It may well be:

Then select "view" > System Information
