Your side of the coin according to this info

RESULT: HackTool.MSIL.Loic.de (Not a Virus) - probably risktool means PUP.
And therefore avast! detects this as such: https://www.virustotal.com/en/file/1b26fcf0da549a47dceefb4e99fd520d63dec3a7cd539d3edcf1d7c1d4a95fd5/analysis/
avast!'s side of the coin -PUP detection.
PUP is a potentially unwanted program.
This means that it is unwanted or risk ware if one has not installed it willfully and intentionally.
So a PUP is no virus - so a PUP is no malcode, -so it cannot be a false positive in that respect.
