HitmanPro says Free AVAST algo.dll is a threat!

I have been running both Free AVAST & HitmanPro for many years on my old Windows XP machine. They always worked fine. But, just recently )10 Feb 2019), HitmanPro keeps detecting two of the Free VAST Virus definitions (called algo.dll) as a threat. But they are not. Why is HitmanPro doing this.

Algo.dll
C:\Program Files\AVAST Software\Avast\defs\19020804\

Algo.dll
C:\Program Files\AVAST Software\Avast\defs\19020803\

I am using Version 18.2356 (build 18.8.4084.409) with Windows XP

Maybe False positive
Can you post Virustotal result here?

Why is HitmanPro doing this.
