I can tell you from personal experience securom can and does mess your system up as it has happened to me several times, my first issue was after installing the Bioshock demo. After installing Bioshock and securom, it proceeded to screw up my DVD drives and render them unusable. Essentially after the install, Windows could no longer see them, regardless of what I did updating drivers, uninstalling the demo/securom, reinstalling Windows, they were simply invisible and unusable. Soon as I formatted my system as in zeroing the damn thing out, like magic they reappeared, reinstall securom and poof gone like David Blaine all over again.
This has happened to me on several occasions, with different games having securom on it. Sometimes it doesn't happen and other times it does, but it only happens after installing a game that has securom in it. As soon as my system is wiped the drives work flawless until I take the risk in installing securom again. securom is not much better than Malware, there are much MUCH better solutions if the publisher/developers feel they really need copyright protection.
