B. Utilize a Linux live disc. Here's why: Utilize a Linux live disc: Booting from a Linux live disc allows you to bypass the infected operating system entirely. This way, you can run a virus scan and remove the infection without the malware being able to interfere, as it would be inactive. This method is particularly effective for stubborn infections that resist removal while the OS is running.

I hate some of these questions that have more than one good answer. Obviously you should update your anti-malware if needed, but the Linux live disk is the way to go if you are already up to date and it failed.

The most appropriate way to remediate the issue of an infection that the antivirus software is unable to remove is D. Update the anti-malware. Updating the anti-malware software ensures that it has the latest virus definitions and detection capabilities, which may enable it to successfully remove the infection. If the infection persists after updating the anti-malware software, additional steps such as quarantining the infected system or utilizing specialized removal tools may be necessary. Disabling System Restore or utilizing a Linux live disc are not typically the first steps taken to address malware infections.
