I think you should try to inquire as to what malicious behavior it contains. It sounds to me like they are reselling rebranded software and have no clue what they are talking about. I was able to get Symantec and GFI to reclassify the previous version as a potentially unwanted tool, which is accurate, unless there is behavior that would classify it as something else.
Sent them an email asking them to clarify. Will see what they respond with...
Got a response from them:
Dear Sir or Madam,
Thank you for your recent inquiry.
The file is riskware and the detection could be renamed to SPR/BitcomMiner.A. The new detection will be available with one of the next VDF updates.
