Oh yea, don't REMOVE anything LG-related... that's a bad idea. FREEZE the app, so it won't run. The LG OS is so interwoven with bullshit apps like that, removing one can cause another to stop working, which you saw. Could have been coincidence, but still better to freeze than to remove. BTW, I froze it and have no issues and it's never running.
This won't be an issue when we get an AOSP or CM version... anything non-stock based will alleviate that issue of LG apps.
