Many antivirus applications offer an option to scan for boot issues. This is a powerful tool to remove malware that is not removed by normal methods. This kind of virus is more difficult to eliminate because it is able to hide in the boot sector, decrypt files, or even encrypt them. It is crucial that you make sure to use an antivirus that can perform a boot scan as this type of virus is not just more difficult to identify but can be extremely harmful.
Avast’s Boot Scan is a very efficient way to detect hidden threats. It can detect threats that are normally overlooked by runtime scanning and can remove it without affecting the functioning of Windows. It may take a while to complete the scan as it must check all the system files. It is recommended to deactivate essential programs when you start your computer and unplug any external storage devices. This will allow the program to focus on internal files. You can also program the scan to run at a specific time when you aren’t using your computer.
You’ll first need to open Avast and then go to the Settings menu. Select the Protection tab in the settings menu, and then select the Boot-Time Scan tile. Here you can choose whether to enable a full or quick scan, download the latest definitions, and configure the actions to be taken when a threat is detected.
