Here is my way to protect my laptop from any hacking activities, ofcourse my way not give any warranty your system will not injected atleast this is your first mitigation

1. Make sure we installed anti virus
2. Make sure firewall is on
3. Use private tab to visit fishy website
4. do not ever install any app, plugin to your systems
5. do not trust public wifi better to connect to your mobile hotspot, hacker can sniff, interupt or steal your data. Trust me, i always doing this when i was young
6. due due diligence while visiting / register on a website
