Antivirus detected but not a virus.

Hi Freelancers, I created a modified bitcoin miner. About a year ago a freelancer already successfully "de-virused" my bitcoin miner. Sadly now it's flagged again as virus and I would need another cleanup. The detections is: Avast Win32:BitCoinMiner-FA [PUP] I already did a lot of work by my own. I found the corresponding HEX code and just need to find it in the source code. So what I'm now looking for is an expert who could take care of that issue and provide me a screencast of the done work. I would like to be able to resolve future detections by my own. It would be great if you're available through skype or teamviewer.
