basically, you are detecting the compression stub of zlib NSIS 3.0 beta2. Please be more careful with your detection and make more targeted detections. If you have more concerns please visit http://nsis.sourceforge.net. i have tried to submit my detection with clam av for weeks no response form them hope this can be resolved soon.
