How do we check hardware for viruses? Is there a guide or procedure for this to be 100% sure any hardware you are dealing with is free from microviruses?
Im particularly concerned about motherboards since the bios can easily be used for malware and motherboards come in open unsealed boxes. Technically nothing is stopping someone from taking it out the box, reflashing the bios with a malicious one and then putting it back in the box.

how am i suppose to know what the fuck this nerd is talking about
You're fucked user, most of the hardware people use run on proprietary piece of shit firmware and there's no way to actually check that it's not doing something malicious unless you want to spend years of your life to reverse engineer them one by one.
Even if you could check for "viruses" (read: everything working as intended) what exactly do you think you can do about them? Do you really think you as an individual can protect against multibillion dollar corporate interests? The national security interests of governments?
Even if you KNEW everything that was going in, it's written into the very infrastructure of everything digital you interact with. The best you can hope for is to secure yourself against as many smaller, less monopolistic interests as you can
Theres nothing that can be done about proprietary firmware indeed, i’m only talking about a third party/someone that is not the manufacturer putting stuff on it.
Oh, well in that case there is a lot you can do about it. Some sites you may be interested in are privacytools.io, and the installgentoo wiki pages on security/privacy. I use ungoogled chromium with ublock and the nanodefender scripts, as well as umatrix set to block third party js. Simplewall is a nice thing to have. There are sites dedicated to testing for leaks of your browser, ports, internet fingerprints, etc. that you might want to seek out as well. And probably most importantly, get a vpn.
I appreciate your input and i do most of this stuff already, but this is not what im talking about.
Im talking about how would we check for malware on hardware that has its own firmware and could be uses for delivering malware with relative ease, like for example a bios. I use motherboards as an example because they come in unsealed boxes and nothing is stopping anyone that can get their hands on it between its journey from the factory to your house from installing malware on it. A second very likely scenario is second hand tech. Generally we’d say to never use second hand storage devices, but when you take into consideration firmware now you have even bigger security problem that cant be solved with a simple virus scan.
My question is how do we check firmware/ROMs for malware basically.
Don't buy used hardware off Ali.
