Mdes sdk v4 3rd party host

A pair of processes with that name popped up in my task manager and lead to files named “wa_3rd_party_host_32.exe” and “wa_3rd_party_host_64.exe” in my Avast folder. I have never seen this before and can’t find anything about Avast using this online, but this process apparently can be associated with malware.

Are these supposed to be here?
