Hi, Can you get a virus/trojan if you drag a DMG file into Stuffit Expander to open it? I am not double clicking on the DMG file to open it? Can certain DMG or ZIP files that are opened by double-clicking on them subject your Mavericks OSX to any virus/trojan/key-logger? There are times I have to open DMG files containing documents and I am concerned that the DMG file can run executable code. Perhaps I have been a PC user too long where clicking on any file(mp3, pdf, zip) can be cause for concern. Thanks.
