Watchout for chrome, the amount of info it saves if you go and look in your app data is scary, every website and its password, credit card details probably the last file you would want out there. Most problems occur when you pick up something online so get a proper browser protector and use a safer browser than chrome.

I know Google and Windows are all "we are about safety" but thats rubbish. Microsoft and google care about one thing data and combining everything you have to online cloud platforms to gather even more data about you. Get avast, or kaspersky. Where possible try not to interconnect devices a breach in one is a breach in all. Get away from chrome bad search results and also saves everything on top of showing you heavily cached results. Get a vpn. Change your default home network name, use network encryption, disable remote access, DHCP, and default ips.
