Dear Sysinternals Community,
I am new user and I will soon use Sysinternals tools for first time. I have problem on my local network. All devices strange behavior and looks infected. I reinstalled OS (Windows 10) and wiped SSD drive with diskpart and clean all command. I had GPT partition. If it will be bootkit diskpart utility should killed it? I afraid that this can be rootkit. Of course any antivirus can't detect anything. I think that this can be firmware infection. So my question is. Should I update my Bios? Or if my system works strange and malware can be there updating bios in windows can be risky? If I wiped my SSD drive and reinstalled OS is there any malware which could survive and it is not malware related to hardware firmware?
Any sysinternal tools can detect firmware malware?
I hope that you can answer.
