If you following these steps than you should be fine:
Keeps Windows up-to-date.
Keeps browsers up-to-date.
Keeps antivirus/antimalware up-to-date. You can run Malwarebytes Anti Malware alongside with any Antivirus for strong protection.
Make sure software firewall is on.
Make sure your router have a firewall as well, because software firewall + hardware firewall = difficult for hackers to penetrate your security without compromise your computer or your router IP.
Make sure your router use WPA2 key.
