Possible bootkit

[White_lotus]

Hi. I'm seriously having trouble with this possible virus, because I'm still trying to erase it and I think that my only possible solution is to install again my operative system.

 

A few days ago I used the AVG antivirus in Windows safe mode and it detected a bootkit. But I say possible because other antivirus can't detect it, even Malwarebytes.

The first time whenever I was using a browser that wasn't Internet Explorer, my computer freezes and I have to reset it. Now I'm trying to turn it on but it turns off automatically, before and after starting Windows.

When I tried to remove the virus with AVG, just a day after it detected it again. Then I made a partition of the disk so I could format it, but it detected the virus in the partition too.

And now when I'm trying to get into the BIOS it turns off as I said before.

 

Anyway, is it REALLY a bootkit that's killing my computer, or it's something else? And before installing the operative system, is there anything else I can do?

Thanks for your reply, MrCharlie. Right now I won't be able to do what you told me; my computer turns off automatically and I think it's because the CPU temperature (I checked it today and the BIOS said it was about 95°C) and I have only around three minutes to use the computer. As soon as I can fix that, I will follow your instructions. Sorry for not noticing that before making this topic.

I don't know if this topic should remain open or closed, but if it is I'll PM you if something happens. Thanks again.
