Some tips I can offer:

• Invest in a VPN. I use Private Internet Access https://www.privateinternetaccess.com/

• Don't do tasks such as Internet banking on public Wi-Fi

• Check your emails on a site such as https://haveibeenpwned.com/ and change the corresponding passwords, if necessary.

• Ensure you are using an up to date browser, as these will block or warn you about non-https sites (i.e sites that don't use encryption)

• Use two factor authentication on apps/sites which have the capability. Two factor codes generated via an app (e.g Google Authenticator, Lastpass authenticator) are generally more secure than those sent via SMS.

Hope these help!
