I still don't understand how people fall for this. It is as easy as having your OS up to date and not opening anything that is from an strange origin (beware of cracked software...) and that's it.
Yes. The thing why people keep falling for it is they tend to get relaxed when it comes to checking the authenticity of the software. But they keep suffering staggering losses just because they find it tedious to check first before they install any kind of software.
