When using Internet Explorer to download Firefox 7 download (I am running Win 7 64 bit) I get a warning that this software can damage my computer, I was wondering what that is all about. I do not want to download it if it will in fact damage my computer. Would you please let me know. I have an HP Pavillion dv7. Michael W. Clark

I wonder whether Internet Explorer gives that same warning for all program downloads?
