Hello.. I'm using Micromax Canvas A 210

[AC Question]

Recently I tried to uninstall some preloaded apps to make some space to update other apps. I got a warning that by uninstalling this app other apps might misbehave.. I'm fed up now.. some apps like CM Locker, DU speed booster, Olacabs, redbus, Omniswipe, vSharemarket and some more just get downloaded automatically.. I've uninstalled these apps like 50 times now.. this happens everytime I get connected to the internet thereby loosing my data. at times it consumes all my data.. Please suggest some remedy at the earliest coz I'm fed up with this uninstalling business.. I have to through this phone. All my money wasted.
