It is very hateful for the hackers to put keylogger on the hotel PCs. However, there are some real and legal keyloggers and you have to pay for them. I have used Micro keylogger. Before I bought it, I had compared many keyloggers. Except for slight differences, many of them work the same way. However, Micro keylogger is the cheapest as well as the most full-featured. After having tried the free trial of kinds of keyloggers, I chose Micro keylogger. It is really a good choice at present.
