How To re-install MY anti-virus app on Gionee M2?

[AC Question]

I rooted my GioneeM2 to uninstall some unwanted pre-installed apps. Later, accidentally my favourite NQ antivirus apps uninstalled. Now, while I am trying to re-install, it is trying to replace earlier apps, and finally filled to install. please help to re-install the app. Thanks.
