Install Devmenu and look in the programs area for one that is installed to the ctr nand. Mkae sure not to uninstall anything that is read. But this happened to me after updating my cfw files and 2 of these icons had showed up. Lucky for me, they were both FBI.cia's installed onto my sysnands nand on accident and they transferred to my emunand so I just found the ones i needed to uninstall and did. If you do find one, search the id of the cia before deleting it though. I found this out by searching reddit
