IT doesn't work to well, it just removes parts of it, but not all of it. Luckily I was able to find a web page that described in detail how to remove Securom from your computer. Took me a while and I had no idea what I was doing, I just followed the person's instructions, often by copy pasting them. Finally got it removed.
I do have a few games that do have Securom on them, Shivering Isles and a few others. I used a small program someone here told me about to scan the discs, put aside the games that do have it and i"ll not play those again.
