How to delete the system updates that automatically downloaded in my phone?

[aqila_k38]

My phone is Acer Liquid Z330. I checked the phone storage and saw that there's no more spaces in it because of the automatically downloaded system updates that are too much in it. I'm trying to clean it up by disabling the Acer Live Updater and clear data of it. I also disabling the AcerAPNUpdater and clear data of it, but nothing happened. Is there anyone who can solve this kind of problem? Thank you very much before, and sorry for my bad English
