Not Turning on Just showing Huawei icon

==Please Help me==

First i tell you what mistake is done by me.

i installed an app "X mod" for hacking "8 pool game" but along-with "other apps like pro user is installed automatically, then i just ignored them. Then one by one apps started downloading without my permission. i just wanted to get rid of this trouble and i uninstalled the download manger (system file). then i even become unable to uninstall any app. then i did a hard reset. then i worked for 1 and 2 weeks (become unable to download anything) and now it is full of virus now.

i turn on power button but it shows only the manufacturers Logo and do nothing.

Please help me
