I am using In focus turbo 5 plus mobile and attacked by malware it automatic open chrome browser and open dangerous site and automatic install app on device what should I do to remove malware from my mobile phone?
First, if you dont like Google apps (like Chrome) opening all the time, you need to distance yourself from Google.
(I do not like it happenening either.)
Second, a new phone will download TONS of things when it is first activated and brought online.
This is technically not malware.
Most of it is what we call bloatware.
Unfortunately, this is typically junk apps that have paid money to the carrier/manufacturer to be included as 'system' apps on any given device.
They are not readilly uninstallable, and even if you can, the space thry consume is never available to you as a user.
The best you can hope for is to disable them, so that they will cease to annoy you.
As for the Chrome thing, first get a better browser.

After setting it up, make it your default browser.
If you dont know how to do this, just ask.
Next, from your homescreen, go to:
Settings
Apps & notifications
Default apps
Assist & voice input
Assist app
Now choose anything besides Chrome or Google.
