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
about #3 this will not protect your browser actually.. just won't store some info from that site on your pc (like cookies and so on)
if you need to install some fresh wallet for new coin - first check it for virus total and the good idea is to run this wallet on virtual machine.. is sand box environment..
