Suspicious of false positive

C:\Program Files (x86)\KWMUSIC\kwplugins\104\Uninstall.exe is detected as UnclassifiedMalware@1

But this application is the uninstaller of my media player, how come it can be a malware??? Is it a false positive?
And anyone here can explain to me what is unclassifiedMalware? This term is quite vague, I don’t know whether it is indicating suspicious item or else. And besides that, I don’t know what to do when CAV detected my computer has a threat which is named as UnclassifiedMalware by Comodo
