If you like to search for "music lyrics" or "free" things, you are engaging in risky cyber behavior. And "free music downloads" puts 20 percent of Web surfers in harm's way of malicious software, known as "malware."

So, can merely copying lyrics (using Ctrl+C) cause malware to be loaded onto a computer?
