Blockchain files flagged by Avast

Hey guys, hope you are all well. I need help with a security issue. My blockchain developer finished my POS/POW blockchain yesterday and sent the files but before it could be downloaded my Avast on Laptop aborted the download and flagged it with
ELF:BitCoinMiner-HH [PUP]

So I did it on my phone and run multiple scans on my phone and hasnt picked up anything from the files. The developer also sent me a virus scan result from see below

Could someone look through the source code to see if theres security issues, loop holes or malicious codes. The only problem is the source is not one script, its in a folder with mutiple sub folders and files as seen in the pics.

Would really appreciate if someone could help xx
