Malware attacks can be disastrous for a system, especially if your system contains a lot of essential files.

And to overcome this, most people use a robust security solution on their system.

But there are some malware programs or codes that can easily bypass these security solutions and can harm your system files.

Popup malware such as Nbryb does not directly harm your operating system and can be easily removed through an Antimalware Scan.

However, some malware such as Rootkits can easily hide deep into the system and can also easily harm your OS files.

And this is where a bootable USB antivirus or a Rescue Disk is required.

So let’s see how to create it and use it properly.

But before that, let’s see some more info about these terms.

What is Rescue Disk or Bootable Antivirus?

Basically, a bootable Antivirus is that type of USB disk which is used to perform a scan and catch the malware without even loading the primary operating system. Because every malware program needs to load in the operating system for execution. And that why it is also known as Rescue Disk.

And now let’s see how beneficial is this…

How is Bootable USB Antivirus beneficial?

For instance, if your PC is severely damaged by malware programs and is unable to start. In that case, you need to remove those malware programs to recover your damaged device back. And this can be easily done by using this simple bootable USB with antivirus installed on it.

Because this is the only way to scan and remove those files from your hard drive without starting the Windows OS. As we all know that the Rootkits only become active when the operating system is loaded.

And in that situation, this is the best option to go with…
