First off, you shouldn't be using pirated software. I would suggest running an antivirus scan and see what it finds, and can remove. If you can't get rid of the bitcoin miner, either with antivirus, manually deleting it, or another way, you will probably have to re-install your computer. As other posters have commented, there is very low likelihood that the police would take the case. It would be like someone going to the police saying the drug dealer cheated me (e.g. you would possibly be in trouble too).
Probably the best way to punish the miner owner is to clean up your computer, and not use torrent sites in the future. Also encourage others not to use torrent sites. People are usually in it for profit, so if they are giving you free software, what else are they giving you? Probably malware to get access to your banking info, in this case a bitcoin miner, etc... If enough people listen, and stop using torrent sites, then business will probably dry up for the crooks!
