Well it isn't a false positive, it is a PUP (Potentially Unwanted Program), which you elected to scan for. Its purpose is to KillIt (file process, etc.) as the name implies and avast can't determine intent or if it is unwanted or not, hence the alert since you asked to check for PUPs.
In that location, part of the HP recovery function and in that location, it isn't unwanted, but there by design.
I have no idea what your D:\ drive is and what is the purpose of the Preload folder ?
I don't know what base_10.inp (if that is an i not an l), can't tell in the image. However, a google search for base_10.inp seems to indicate it too may be related to HP and the recovery partition,

You could also check the offending/suspect file at:
VirusTotal - Multi engine on-line virus scanner and
report the findings here, post the URL in the Address bar of the VT results page. You can't do this with the file securely in the chest, you need to extract it to a temporary (not original) location first, see below.
Create a folder called
Suspect in the
C:\ drive. Now exclude that folder in the
File System Shield, Expert Settings, Exclusions, Add, type (or copy and paste)
C:\Suspect\* That will stop the File System Shield scanning any file you put in that folder.
