It was discovered today that Ubisoft has been shipping a rootkit in the form of a browser plugin with the PC version of Assassin's Creed: Revelations. Granted, they've already issued a patch to fix this, but the point remains that their poor testing means that anyone installing this game would also install a backdoor on their PC, allowing any malicious group or software to take control of it remotely.

Stuff like this is why I refuse to get any Ubisoft games for the PC anymore. Between poor security checks, extra-draconian anti-pirating software damaging PCs, always-online access required even for single-player games and whatever is coming up next, I don't feel welcome to actually purchase their products.

They claim that piracy is hurting their sales. That's possible. However, their anti-piracy measures are so bad that they cause me not to purchase their games, so they also lose sales from legitimate customers.
