That's not true at all. If it's an [Caution: ExecutableFile], it does not mean it has to be a virus. It's just a simple form that most amatuer hackers tend to use. Keyloggers and trojans can be embedded in other forms of files. I don't know if they can be embedded in excel files, but I'm just saying that just because it's not a [Caution: ExecutableFile], doesn't mean it's 100% safe. Anyways, cool calculator/log thing. I may give it a try when I become members again, if I ever do.
