Or worse than a virus?

I picked up Dirt 3, which uses the steaming pile known as GFWL. Naturally it wouldn't log in to my account, this thing is krap, after all. I can log in to the account from the web site, but in games it refuses it. So I had to make a new account and lost all my Dirt 2, GTA VI and any other GFWL infected save files.

GFWL has done more damage to my machine than any virus I've had.
