Most email viruses that disguise itself as JPG is just exploiting one Windows Explore feature: hiding file extensions of known file types. So a virus named vir.jpg.exe or something similar will show up in your email as vir.jpg instead. If you look carefully, the icon is different. Always uncheck the above option in Explorer's Folder Option menu and you will never be fooled again. You can embed any binary code into a image file but it will never get executed unless you also have some special software designed to extract them and execute them. ----- Original Message ----- From: "Christian Kuiphoff" <[EMAIL PROTECTED]> To: "Libretto" <[EMAIL PROTECTED]> Sent: Friday, February 08, 2002 11:19 AM Subject: RE: [LIB] List problem? > Date: Fri, 8 Feb 2002 08:14:43 -0800 (PST) > From: Christian Kuiphoff <[EMAIL PROTECTED]> > Subject: RE: [LIB] List problem? > > You could put any code you wanted in the "Makernote" section of > the EXIF section.
