I posted about EA's Origin service when they first announced it. At the time, the big concern with the service was that running it would effectively allow EA to access your computer and do whatever they want with whatever they find there.
Now comes a report that running Origin exposes your PC to being hacked remotely. Thankfully, it's easy to avoid this problem: don't buy EA games. Or, if you simply must run some EA game, don't ever leave Origin running.
