New phone with pre installed malware

[AC Question]

Hello,
I have just recieved my new android phone, however on boot i get adverts coming up.
I installed AVG and Lookout and 2 malware detections have been found

One called: KKBrowser
One called: Processor

There is also a DCShare which i am suspicious of

Also Lookout found a 'root enabler'? What is this?

When i try and uninstall these i am unable to because they have been pre installed by vendor?

When i look at what these apps are capable of it is:
read phone status and identity,
approximate location,
read your web bookmarks and history
modify or delete the contents of USB storage
disable your lock screen
download files without full network access
close other apps
run at startup
draw over apps
control vibration


Why would any pre installed app need any of that? I have disabled them but please tell me if this is safe and what you would do?

Any help is appreciated,
Thanks,

Scott
