Is this UE installation error a false positive from virus protection?

Problem: Installation of UE 4.26.4 fails during the final verification phase. System Shield - part of System Mechanic by Iolo Technologies - creates a pop-up action (see attached).
The apparent issue is the file ‘DELTAS.EXE’ that appears to be associated with ‘W32/Agent.CHQ.gen!Eldorado’

Questions: Could this be a false-positive by the heuristic Ai in the System Mechanic malware detection?
How might I overcome this and get a clean, uninterrupted installation of UE?

Any help or suggestions would be appreciated. Thanks.

seems so…
