I decided to remove it because I did a scan of it from virustotal and it has many malicious stuff in it, but I scanned with my own anti-virus and nothing came up. So I don't trust it currently.
I have restored the Mr Mix game page, as I have updated it with a new version and this doesn't have a virus in it. As long as you have Windows Defender or a decent anti-virus program, your system won't get infected.
