Always use CCleaner before you start your web browser and after.
Use Firefox and open "new private window"
You can even use a Virtual Machine and use to do your internet habbits with.
Few good Softwares you can use is VPN, Malwarebytes, Ublock origin (have WebRTC marked), firewalls installed on your computer.
