I'm not sure about my system so I want to completely wipe my HDD and reinstall Windows 10. But I realized that an infected system can also infect a USB bootable drive. Unfortunately, I don't have access to a trusted system to create the USB bootable drive. I scanned my system with a couple of antivirus software (Malwarebytes, Windows Defender offline, Kaspersky, etc.) but still, I cannot be sure because of sophisticated malware, like rootkits.
