I do many things to protect myself from problems. For example, instead of using Microsoft or Apple, I use Ubuntu. I try to use a proxy. I try to change my DNS. I try to use encryption. I try to use the best web browser I can. I use Firefox. But, Brave is probably better. I'm saying this because hackers can sometimes find ways onto your computer in order to hack into email, etc. So, there is remote access (backdoors). Most viruses are written for Microsoft. Most computers run Microsoft as an operating system. I don't change my passwords.
