1. What can viruses that infect these places (MBR/GPT, boot sector/VBR, BIOS/UEFI firmware, the EFI system partition) do to me? According to the coding of this virus, these viruses can spread from my computer to my microphone, camera, files, or information, can access the camera, microphone, file or information of the devices?

2. Can Eset Live guard access and detect threats where ESET can scan?

I'm asking these @JackE

Ok, when I asked the ESET moderators, they didn't give %, but someone said they can access UEFI and someone said they can access all of them. I'm also confused with the norm, how do I detect it if something is infected here then? @JackE

Why do you say there will be less than 50% detection?

And I think access is also important, one day advanced threat protection will definitely solve the malicious actions of the virus or add it to the virus database. @JackE

you said nothing is 100%, so 50% wouldn't be 50%?

So you just guessed? You have no valid evidence for the probability of this to be less than 50%.

Do you have valid or invalid proof that it is 50% or less?

Do you have any invalid proof that it's more than 50%?

About what?

But you don't have any valid or invalid proof that you have more than 50%, less than 50%, or 50%, do you?

You may be good at guessing, I have no complaints about it, I'm just asking if you have any valid or invalid evidence or reason.

So it's based on your experience in guessing?
