Yea I don’t know.. Just know when I opened this jpg file. I found the 6 files I just deleted.. Anyway don’t know.. Maybe it was a hidden ext. but I made sure that show known ext was turned on.. I have also read that there was the ability to embed a script file.. Sad thing is I was unable to detect the troj with any scanner.. But was walked through getting rid of the thing anyway ill have to see if I can find that article.. -----Original Message----- From: Lawrence Young [mailto:[EMAIL PROTECTED]] Sent: Friday, February 08, 2002 1:35 PM To: Libretto Subject: Re: [LIB] List problem?

Yes, jpeg is an image compression method and .jpg is the extension commonly given to the jpeg compressed files. The decompress of the jpeg file only happens with the help of JPeg capable programs like browser and photo editing software. You do not execute the jpeg file because you can't. However, it is possible for someone to rename an executable file into something like vir.jpg or vir.bmp. And in normal cause, this will not cause any problem in Windows as Windows will check file extension and load the photo editing software to load the file and display some error message since it is not a jpeg file. However, in the native Windows API calls, you can let Windows execute any file regardless the file extension as long as the format of the file is that of the windows executable file (or called PE format). This can only be done through 3rd party software, however. Maybe your IRC software have this feature to execute those files if instructed. ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://libretto.basiclink.com/archive - Archives http://www.picante.com/~gtaylor/portable/faq.html - FAQ -------TO UNSUBSCRIBE------- Reply to any of the list messages.
