Are there any legitimate keyloggers that work with Norton 360?
The problem is that once a keylogger is identified by an antivirus it’ll be blocked. You have to disable the AV or switch keyloggers. Most, if not all the commercial ones have been identified and are in most every virus database. You might want to look into rootkits. A rootkit (or root kit) is a special “driver” that hooks into Windows under the filesystem level. You can make files appear “invisible” to the operating system (as in, not show up in Windows Explorer, Search, task bar, process list, etc.) even though they’re still running or still on the HD. You have to actually circumvent the OS by reinstalling it or putting a new one on before you can see the file (even though it’s running), unless the root kit is disabled. It might help you out.
