When I run HitmanPro, it says that mpchc64.exe is a trojan. A virustotal analysis seems to show malicious flags triggered by several vendors.
What is going on? Why does a file by Media Player Classic team contain a trojan?
Solution:
That is not the version of Media Player Classic installed on your computer, and indeed is a virus. Why?
Look at the folder the executable with a virus was found in – a folder which appears to be for temporary or cached files used by Adobe Flash Player. In terms of the actual virus, it appears to be a variant of Win32/BitCoinMiner.G, which is indeed a real virus (using your computer power to mine bitcoins).
Lastly, you should be aware that the Product/Publisher/Descriptions contained in a .EXE file are set when the application is compiled. They are in no way “official” and can easily be spoofed.
If you’re wondering how that file got on your computer, it could possibly have been a drive-by download. Make sure all of your antivirus software is up to date, and if you use any third-party addons in your web browser (especially Java or Flash), make sure they are always up to date (or preferably, disabled!).
