DMD and PKD are two of many services (programs) that Apple are 
running in the background on your computer to make sure that your 
computer functions correctly.

They are shipped with your computer and are located here:

/usr/libexec/

Do not remove them!

After an install these services may have to do cleanup. If this 
problem persist, I suggest you take your iMac to a local Apple 
service location.
