Ali is a shopping app and I can't imagine it being a preinstalled app but I have to ask anyway...
Was this a preinstalled app?
When you say uninstalled, you're sure you are removing the app from the device and not just uninstalling the updates?
Now that's out of the way...
Are all of your apps from the Play Store, Amazon App Store or your manufacturer's app store? Installing apps from unsecure places, like random internet app stores and APK markets, can lead to nefarious apps on your device. These apps can come with too many permissions. Permissions that when granted can cause a ton of other issues.
