@Mrlucci -- how can I ...

After taking 3 minutes to read: Help: I Got Hacked. Now What Do I Do? | Microsoft Docs

i.e., an influential person who really "knows his stuff", the short answer is YOU CAN'T.

As for "root-kits", see: RootkitRevealer - Windows Sysinternals | Microsoft Docs

It might indicate the presence of a "root-kit".

what if the malware had infect my motherboard how can i remove it ?

The only part of the motherboard that might get infected is the BIOS/UEFI code.

Following-on to Johannson's article, I doubt that you can remove it, except by replacing the BIOS firmware, starting from a trusted source.

Thank you very much for the reply Mr Jesper

But i have another question 

If it cant be removed why there is a lot of antivirus told us these antivirus could remove a rootkits

Like malwarebytes anti-malware it had a tool especially for that ?!

What if i flash my bios after wiping my hard drive 

Using usb ?  could that make my computer new without any malware again ?!

I am not Jesper -- I just cited his article.

But i have another question. If it can't be removed why there is a lot of antivirus told us these antivirus could remove a rootkits. Like malwarebytes anti-malware it had a tool especially for that ?!

A rootkit can be compared to a hacker getting a key to your home.

The hacker can return to your home, many times, and steal some items everytime they visit.

The rootkit gives the hacker complete access to your computer, with the ability to "plant" other malicious software onto your computer, and all the computers inside your home network.

Changing the lock stops the hacker from entering your home, but it does not detect and remove any "other" items that the hacker has left -- web-camera(s), listening devices.

Similarly, while a company's software can remove the rootkit software, the software may not find all the "other" malicious software.  So, their advertising is correct, but only as far as it goes -- to "remove" only the rootkit.

What if i flash my bios after wiping my hard drive?

Could that make my computer new without any malware again ?!

For the small price of a new SSD, I would not try to "reuse" the previously-infected disk-drive. I would purchase a new disk-drive.

If the BIOS is "infected", then using a compromised BIOS to try to "flash" it may only APPEAR to be successful.  Ouch!

@Mrlucci -- since that article written in 2009, I find it really disappointing that the following search:

   http://www.google.ca/?q=site:microsoft.com+remove+virus 

returns some articles, apparently written by Microsoft employees, that contradict Mr. Jesper's conclusion.

All of those employees really should read Mr. Jesper's artifle, and then re-assess their opinion.
