therenegadeoffunk69, a lot of things that 'hackers' use will be screened as malicious by scanning software. A prime example would be cain and abel. Now that said, I don't know anything about that software that you're trying to download, so I would always assume the worst.
OP, like I said above, I would always assume the worst. Downloading and using a third party keylogger creates a HUGE risk of you becoming infected. So rather than doing that, I'm going to tell you to make one. It'd be a lot more beneficial. And don't tell us to not to you to do something. Because obviously we're the more skilled people on the subject. Creating a keylogger is not that hard. You could very easily look up the code for a simple keylogger and compile and run it yourself. That way, you'll at least be able to see what you're running. And you can still be lazy and not actually put any kind of intellectual input into coding your own program.
For those about to hack, I salute you.
