Hi! No, the phone comes with it, and there will be conflicts when you install it.

A more detailed description of the problem will help netizens understand the troubles you are encountering and help you solve the problem more accurately. Thank you for supporting Xiaomi phones!

I never install it, including my computer, but I have to develop good Internet habits and don't install junk software. Garbage ** do not enter.

Pack it up, that's for sure.

My 2a 360 is recommended to install antivirus software.

Just kidding, how can I not install antivirus software? If you don't go online or plug in a USB drive, you can't get drugs. Can it be done? When you get hit by the awesome virus and lose all the information, it's too late to regret it!!

If you don't pretend to be an antivirus, your friend must have used some kind of tool.

Computers don't have antivirus, it can't be virus-free.

Alternatively, you can use a mirrored desktop similar to the shadow system to operate the computer.

If you have the ability to manually check and kill, it's no problem, otherwise, hehe. You know.

If you want to get off the movie, just pretend, the little red umbrella, which takes up less resources and doesn't affect the overall speed, hehe, after all, do you want to get a movie.

Hehe, I don't know what the logic is, but if you use a computer, there is no account password on it, and it's okay to use it normally.

If you have an account, install a 360 that doesn't take up resources.

360 is antivirus! Do you listen to him blowing water?

He might have reinstalled the system in the spirit of poisoning!

Recommend Jinshan, it's free now, and the anti-virus ability is also very strong, and it's very small, only 30m

It's better to pack one, and it won't be more than a card anyway.

The idea that a laptop is the same as a desktop is grossly wrong!

Yes, you can turn on monitoring.

You can't take it lightly, and the current anti-virus is chicken ribs!

Yes, it comes with Rising Monitoring.

Hello. The MIUI system of Xiaomi phones and Redmi phones comes with security and system management software, and it is not recommended that you install third-party security software, as installing these software may affect the normal use of the phone.
