Usually, this type of malware operates in such a way, that it tries to mislead you about its real nature and intentions. It may often appear like a harmless, or even useful program, document, funny image, link, email message or attachment, etc. and trick you into clicking or installing it, believing that you are getting some free or useful feature.
