New Laptop

First, I never recommend using a program to decide what should be removed! Too many people end up breaking the computer by removing things that shouldn't have been removed. You just got the laptop, use it awhile and then look at some programs you might have not used. Post here and ask a) what does this program do and b) can I safely remove it.

Second, after you've used it awhile you'll discover what you might want to do but don't have a program to do it. Then it is time to post and ask for suggestions.

 

I'd stick with Windows security program. It works well and doesn't add heachaches when a Win 10 update might break something in a 3rd pary security program.

Try Edge. I always have at least 3 browsers on a computer/android device.
If you like Edge use it; if you are used to another browser, like FF, download and install it too and see which you prefer. Don't bother installing Chrome because Edge is based on that so it would be like having 2 browsers with the same engine.
