I recently bought a M.2 external caddy, I've not used it yet but could be useful without the constraints of a drive running in a PC.

But when you throw it there is only scanning. As far as I know virus cannot be found in scans if encrypted @HarborFront

Look. If scanning catches a virus it'll show up otherwise there's nothing for the AV to show.

Definition of a boot sector virus

A boot sector is a reserved section of a disk that contains the code and data needed to start the operating system (OS) of a computer. A boot sector virus is a type of malware that infects a system’s boot partition or the Master Boot Record (MBR) of a hard disk. During startup and before security software can be executed, the virus executes malicious code. Once a computer is infected, a boot sector virus will try to infect every disk that is accessed on the infected system.



If the virus is encrypted then the virus cannot perform its malicious actions without itself decrypt first. That is to say, the virus is useless if it stays in its encrypted state. AV software like Avast can detect during boot time when the encrypted boot sector virus decrypts itself to cause malicious actions. If malware prevents Avast Antivirus from running in normal mode, you can schedule Boot-Time Scan to run in Safe Mode.

Look, I'm asking you this:
If there is a virus in the boot partition, what can I do to delete this virus?
@CyberTech
Start from scratch. A clean PC is better than a disinfected one.
  • Backup all your important data to an external drive, or the cloud.
  • Format the whole partition / disk drive.
  • Reinstall OS with GPT/UEFI (not MBR/BIOS)
  • Don’t download anything from untrusted sites or warez.
Microsoft offer this tool for Windows 10, it may be useful:

Else follow this guide for GPT

Look. If scanning catches a virus it'll show up otherwise there's nothing for the AV to show.

As for encrypted boot sector virus are you infected with one now? If yes, then post at the Malware Removal Section. There's one expert there to help you
We have suggest this before, they appear to have abandoned ship due to minor concerns over uploading .txt files.

There are a few different ways to format the boot sector, depending on what you're trying to do. Here are some general steps to follow:

1. Open the Disk Management utility in Windows 10. You can do this by right-clicking on the Start button and selecting "Disk Management" from the context menu.

2. Locate the disk that you want to format the boot sector for. You should see a graphical representation of all your disks and partitions in the bottom half of the Disk Management window.

3. Right-click on the partition that you want to format the boot sector for and select "Properties" from the context menu.

4. Click on the "Tools" tab and then click on the "Check" button under the "Error Checking" section.

5. Follow the prompts to check the disk for errors. Depending on what the utility finds, it may suggest formatting the disk in order to fix the errors.

6. If you need to format the disk, right-click on the partition again and select "Format" from the context menu. Choose your preferred filesystem and follow the prompts to format the disk.

Note that formatting the boot sector can be a risky undertaking, especially if you're trying to recover data or repair a damaged partition. Make sure you have a good backup of any important files before you proceed.

Hello, I got a little late reply, but I want to ask, can this virus pass to other devices via wifi and come back to my computer after I format the disk? @Ink
