cannot typically obtain. Additionally, BIOS flashing usually requires user confirmation and cannot be done covertly by a virus.
8 No. Flashing the BIOS is a complex process that typically requires specific software and a legitimate firmware file from the manufacturer. A virus cannot initiate a BIOS flash on its own.

Can a rootkit survive a BIOS flash The BIOS (basic input/output system) is firmware that resides in memory and runs while a computer boots up. Because the BIOS is stored in memory rather than on the hard disk drive, a BIOS rootkit can survive conventional attempts to get rid of malware, including reformatting or replacing the hard drive.
What is a BIOS rootkit A BIOS rootkit is programming that exists in a system's memory hardware to enable remote administration. Rootkits may be installed for legitimate purposes, such as digital rights management (DRM) or data or device security but they may also be targets for persistent attacks.
What can a rootkit virus do A rootkit allows someone to maintain command and control over a computer without the computer user/owner knowing about it. Once a rootkit has been installed, the controller of the rootkit has the ability to remotely execute files and change system configurations on the host machine.
What effects does a rootkit have on a computer Potential consequences of a rootkit include: Concealed malware – Rootkits allow attackers to install additional malware on infected computers. They hide malicious programs from users and any anti-virus software installed on a computer.
Persistence – Rootkits are notoriously difficult to detect and remove. They can stay hidden in a computer’s memory, evading traditional malware scanning tools.
System instability – Rootkits can interfere with the normal operation of a computer, causing crashes, slowdowns, and other performance issues.
Data theft – Rootkits can be used to steal sensitive data from a computer, such as login credentials, financial information, or personal files.
Unauthorized access – A rootkit can provide an attacker with complete control of a computer, allowing them to access sensitive information, install additional malware, or use the computer as a launching pad for further attacks.
Network compromise – Once a computer is infected with a rootkit, it can be used as a point of entry into a larger network, giving an attacker access to other devices and potentially compromising the entire network.

Does resetting PC remove rootkit In rare cases, this can become infected with malware. Hence, doing a factory reset will not clear the virus. A rootkit is a program capable of providing deep ('root') level access to your OS. Their original purpose was to provide authorized users with administrative access to a device.Will factory reset remove rootkit A factory reset will generally remove viruses, but a few can still survive it. Here are some ways this can happen: It's rootkit malware: A rootkit is malicious software that provides privileged access to the operating system of a device.
Can malware infect BIOS Yes, malware can hide in BIOS by infecting the bootloader. The bootloader is a small program that loads the operating system into memory. If the bootloader is infected with malware, it can infect the rest of your system, including the BIOS.

Overall, rootkits can be a serious threat to computer security. They can hide malicious activities, compromise system integrity, and allow unauthorized control over a computer. While resetting a PC or performing a factory reset can remove some rootkits, there are cases where they can survive these measures. It’s important to maintain up-to-date security software and regularly scan for any signs of rootkit infections.

Can a rootkit infect motherboard
Hardware or firmware rootkit
Hardware or firmware rootkits can affect your hard drive, your router, or your system's BIOS, which is the software installed on a small memory chip in your computer's motherboard.
Is rootkit a boot sector virus
A boot sector virus is a type of rootkit virus, and these terms are often used interchangeably.
Will a system restore remove a rootkit
Using an antivirus program and doing manual clean up are not options for removal. Note that using System Restore is not an option, either; rootkits infect the very core (the root, for lack of a better pun) of your machine so any restore point is most likely infected by it, as well.
Are rootkits removable
You can use a rootkit removal tool or antivirus software, such as Avast Rootkit Scanner, Malwarebytes, Kaspersky, Lynis, or McAfee, to remove malicious software from your computer. Rootkit removal software delivers several scans to ensure rootkits and other types of malware are not infecting your machine.
What virus destroys BIOS
The Chernobyl virus could sometimes cause the blue screen of death to appear on Windows computers. The second payload would rewrite the flash BIOS chip by replacing critical boot code with junk code.
Can hackers hack BIOS
If the BIOS isn't properly protected, it can get infected with malware or hacked. If this is the case, cybercriminals can hack directly into the laptop's firmware, read out data or even manipulate it without being detected.
How do you know if your BIOS is infected
The most common sign of BIOS infection is boot up trouble. Your computer may start acting weird during start up or even not start at all. Specifically, the errors “No Boot Device Found” and “Invalid Boot Disk” are omens of BIOS malware.
Can your BIOS be hacked
If the BIOS isn't properly protected, it can get infected with malware or hacked. If this is the case, cybercriminals can hack directly into the laptop's firmware, read out data or even manipulate it without being detected.

What is bootloader rootkit
Bootloader rootkit
The bootloader mechanism is responsible for loading the operating system on a computer. Bootloader rootkits attack this system, replacing your computer's legitimate bootloader with a hacked one. This activates the rootkit even before your computer's operating system is fully loaded.
