Hello - checking mp3tagv311setup.exe against VirusTotal triggers an alert by Jiangmin: Trojan.Generic.hcksl. Everyone else seems to be OK with the executable.

Apparently, virustotal is a little nervous.
It's most likely a false positive. Jiangmin is a Chinese virus scanner, so it's difficult to report as false positive and verify my assumption.
As always: don't install if you don't trust
