Q: System extension problem

I get a window popping up with Yosemite 10.10.5 that says that "The system extension "/System/Library/Extensions/Accelsior.kext was improperly installed and cannot be used. Please try reinstalling it, or contact the product's vendor for an update.

 

Not a clue have I. I guess that Accelsior refers to a hard drive that I had installed but is installed no more. Can I just delete that file?

 

Other than the pop up, the computer is running fine.
