the only thing im gonna connect my new router to is a new pc so therefore its not possible for it to be infected again because i wont re connect any old items that might have malware, you can confirm thats a bullet proof solution to this problem that and avoiding sketchy links and websites? what are you saying when i plug it into my LAN
No, I cannot confirm or guarantee what you stated. Since you don't know if, how or any detail of the supposed attack, it could very well be that with all new equipment the same thing will happen within 5 minutes of turning it on. As I've said, it could be something as simple as a default setting in your router that needs to change (remote admin access for example) or a million other things.
Again, to be clear, you must (if you want help) provide (at a minimum):
- some evidence of the attack, or at least something more than "a rootkit on my router, PC and printer"
- only then can it (hopefully) be determined how the attack infiltrated the primary device (example a known vulnerability in a router with old firmware and if it is even remotely possible that it would spread to other devices
Again, buying all new hardware also wouldn't help you if the first thing you do is go to some sketchy site to download your favourite game, utility, browser addon or what, thinking it is safe when it isn't this introducing the malware into your inner lan. No firewall or configuration change or new hardware will stop that sort of thing. What if it is simply malware that has taken over one of your data files, or in your cloud? I'm not sure how much more strongly I can emphasize the need to find out at least what, if any, malware affected you
What seems like 100 posts in, there is still no evidence (logs?) of an actual attack, or the details of how it manifested, or how rootkits were exposed, or their names or frankly anything useful to help you.
Based on this, I would ALMOST GUARANTEE THAT IF YOU BOUGHT ALL NEW HARDWARE, YOU WOULD LIKELY BE ATTACKED (if there was an attack) again in short order.
But, all we can do if offer our advice. If you decide to spend a bunch of money (unnecessarily IMO) that is of course your option to choose.
