A widespread [[malware]] company named itself NSIS Media. NSIS Media and NSIS are not related by anything but name. As with everything downloaded from the Internet, a reliable download source should be chosen to avoid this malware.
Several antivirus companies have labeled plugins such as NSISdl, which provides HTTP downloading functionality, as trojans.<ref>[http://forums.winamp.com/showthread.php?threadid=189414 WINAMP.COM | Forums - nsisdl.dll contains Download.Trojan]</ref> This is also incorrect. While NSIS is a scriptable system and thus could be used to create malware, that is not its primary purpose and this condition in fact applies to all [[Computer programming|programming languages]].
