Has anyone ever seen this (NSIS.Library.RegTool) before? Located in my Win32 subdirectory. One of my faithful security sentinels (DCS WormGuard) spotted this one trying to execute today. Happened when restarting my PC just after installing FileAnt (which by the way is a nice appy). Not sure if the two are related or not, but the file had a date of Sept 2004, which makes me think it's not. Just thought I would check. Google was not much help. Thanks in advance!
