"GTA 4 PC adopts SecuROM
Rockstar announced that the PC version of Grand Theft Auto IV (to be published Wednesday 3 December), will use the famous copy protection SecuROM. The game will require an Internet connection during installation and you will have the DVD permanently in the drive to play. However, there will be no limit on the number of facilities as we see more and more these days. So you can re-install the game as many times as you want."
