Most of the rats i used like prorat are caught by the avs and techniques i found to camouflage them fail. I found a link on the internet telling me to add nop bytes to its end, but i dont know what nop is. How do you hide rats? What are the best techniques for that?

NOP stands for No Operation. Search for it in some assembly reference. Have you googled it before asking?

Now talking about the 'rats', why don't you try to create your own? AVs look for viruses' signatures, and most of the common rats you find to download are pretty common. Adding NOP bytes do not change the virus signature at all, so it will not help. It is an old technique that long time ago worked, but not anymore.

Yes I did. I typed NOP byte, and it said no operation, but I didn't know such a byte exists.

I learnt visual basic programming, but I find it hard to read characters typed. Do you know some language that would be good to build your own keylogger?

Any language is good enough for your use. If you know visual basic, practice with it. This link might help you:

By the way, look for visual basic threads. They might help you if you want to create a keylogger. Google if you don't know what that means.
