As long as the hackers don't have access to your computer, the things that you are overly concerned about like installing drivers or something like that won't happen because they also have to have initial access in order to be free with our computer so when we don't do anything that threatens our computer then I don't think it will be a problem.

Actually the steps you take are very good, but I agree with some people in this case we don't need to be too paranoid. because in the end the worries we do actually make us careless.
Just do what you have to do, like securing your wallet, securing your seeds and never store anything valuable like seeds on a PC or in the cloud which is vulnerable to hacking.
Being cautious is important because anticipation is much better but don't be too worried about what you're doing because paranoia can make us more stupid and make us easily infiltrated by hackers.
