I used to have a-squared as a antispyware for testing purposes. The process you are trying to find out about is in fact part of a-squared. It is used to get a signal whenever a new process pops up. If this is still running on the PC and/or is still being flagged by your AV then, it is a false positive. If you have discontinued the use of a-squared then, you can safely delete this file.
More info can be had at a-squared forums :

Hope this helps.

Researched mchinjDrv on the web, it appears to be used legitimately by various AV programs, so is probably safe to leave on the PC.
