A boot scan is a powerful feature offered by many antivirus programs that can eliminate malware that can’t be removed by normal methods. This kind of virus is able to be hidden in the boot sector or even encrypt files. It is typically more difficult to eliminate than a regular runtime scanner. It is crucial to make use of an antivirus that is able to perform a boot scan as this kind of virus isn’t only more difficult to detect but also extremely dangerous.

Avast’s Boot Scan is an efficient way to detect hidden threats. It can detect threats that are usually missed by scans that run at runtime and is capable of removing it without affecting the functioning of Windows. It can take a long time to run the scan because it will be checking all of your system files. It is recommended to disable any non-essential programs on startup and unplug any external storage devices. This will let the program focus on internal files. It is also a good idea to schedule the scan for times that you won’t be using your computer for any other purpose.

First, open Avast and then select the Settings menu. Once you are in the settings menu, select the Protection tab, then click the Boot-Time Scan tile. You can choose to enable a complete or quick scan, install the latest definitions, and set the actions that are taken when a threat has been discovered.
