I've used my acer chromebook for a few years and really like it but a few keyboard keys have been sticking and is very annoying when you write a lot. So for $159 I decided to purchase the AO1-132-C3T3 with windows 10 yesterday.
 
Haven't opened it yet but wondering a few things: What's the best way to not worry about viruses? On my w7 laptop I only used microsoft security essentias and was pleased with that, is there something similar and is it already installed?
 
Will there be programs that are not needed that I can uninstall or set to not start that can save memory?
 
Can it run apps like instagram or snapchat?
 
I appreciate any tips to help my new laptop run smoothly, thank you.
