Ok I have an old laptop here at my house my daughters were always going on. Well one day we had a guest over and they used the computer and installed something that almost wiped my home network. After that I took the computer away from EVERYONE. Anyway yesterday I installed Linux Mint 64bit on it. I created a admin account for myself and a guest account with basic privlages for everyone else (no installs or setting adjustments). I also enabled the Firewall which was off by default. Then I installed Chrome and Ad Blocker. Is there anything else I should do? Any other settings I should adjust?
