Some keyloggers are still undetectable, so I was wondering since we can "join" files with certain software, if there was any apps to "unjoin" or detect the union of 2 files.
Exactly what software do you speak of? I've never seen a virus attached to a .jpg or anything of the sort...only installers that install more than you know about.
I was reading up on some keyloggers that can be "pre-set-up," attached to say, a .wmv file, sent to someone via e-mail and when they open the file, the keylogger installs quietly. Maybe I misinterpreted the information I was reading?
