The perils of piracy
Malware has long been a staple of CD cracks and pirated games.
I buy my games, always have. But I freely admit that shoving the disc in the reader just to play quickly got on my nerves. I used to have a fairly reliable No-CD site, so I could avoid that hassle. Slowly but surely, even that site got taken over by the scum of the Earth and its cracks were no longer trustworthy.
These days, the problem is solved because I use Steam. GOG is also an option.
But you buy your games. Cracking them is just asking for trouble.
