It appears to be part of Microsoft Windows Malicious Software Removal Tool and according to the MS article that would be the latest version. It may be trying to contact MS for updates and your firewall is catching it.

There are also viruses using that file name but generally they show up in random places such at the root of C or even other partitions. Judging by the location of yours, within a update folder, it seems safe. The key word here is "seems" so a continued blocking of it until such time as you can deem it perfectly safe is in order.

Another option is to download the official MS file from the link given below:

According to this:

39 seperate av scan software apps. reported WINDOWS-KB890830-V2.3-DELTA as being clean.
So why is ZoneAlarm flagging it?
For peace of mind, you might try an online av scan:
