I am having a problem with nmap-I scan an IP and it always (no matter if the computer is in my network) says the computer is off. Some of the computers I know are never shut off. I need a list of tools I can use to scan computers, find out what OS they use, etc. Also, (this sounds fishy, I know) I need some Windows virus and rootkit codes to look over and see how they are built and try to write counters to them. Google does an excellent job of telling you that 3,647,901 results came up, and only shows the first 100 pages or so. I have searched everywhere. Yahoo, Google, Dogpile, MSN, etc.
Can anyone help?
<edit>I got some tools from the recently made sticky, my other questions still stand.</edit>
