( i removed them for a reason before) same error message appears. please help me..

Try clearing cache for Play Store under Settings -> Apps -> All and see if that helps. If not, do you get this message if you try downloading on another connection (WiFi, mobile network)?

Have you tried this on another internet connection? Looks like you get a corrupted download which indicates a problem with your current internet connection.

why must have mcAffe antivirus???

That's because you've disabled the background data.

You must have around 500mb-1gb internal memory space free for installation of large apps, clear cache from play store and u'll see it run perfectly. I got the same installation error in my sony xperia SP after i downloaded asphalt 8 (1.6 gb).
