Installed by ZoneAlarm; MS Outlook spam filter; resource-hog; optional component

Zemana alerted that it was logging keystrokes, I question that it a Zone Alarm process would be doing this.
It's part of the ZoneAlarm Internet Security Suite's "Junk E-mail Filter." To disable it, go to the ZA preferences panel /E-mail Protection/Main/Junk E-mail Filter and click the "Off" radio button.
It is valid only if you are using MS Outlook. For any other email client, it serves no purpose and should be disabled. It is a bit of a resource hog. To disable, within your Zonealarm program, go to the Email Protection section and turn all options to OFF. Reminder, these ONLY work if you use Outlook so do not feel threatened by having them off. As stated, the executable is mantispm.exe. New upgrades by Checkpoint/Zonealarm often have issues with getting this to function right and it is common or their Technical Support to place blame on user's system up until the day they release a patch.
Dude that claims using a bank PIN online is bogus. No banmk uses insecure PIN online. He's a firewall competitor - idiot.

ZA (actually MailFrontier Desktop application) Spam blocker, but does indeed monitor keystrokes for some odd reason. If you are using ZA, it can be disabled by disabling Junk Email Filter in ZA.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem.
