Many antivirus applications offer a boot scan, which is an extremely powerful tool that can eliminate malware that can’t be removed with normal methods. This type of virus is more difficult to remove because it could hide in the boot sector, and encrypt files, or even encrypt them. It is essential to use an anti-virus that can perform an analysis of the boot sector because this type of virus is not only difficult to identify, but can also be extremely harmful.
Avast Boot Scan is a powerful way to identify hidden threats. It is able to detect threats that are usually overlooked by runtime scans, and remove them without disrupting Windows operating. It can take a long time to run the scan because it has to check all of your system files. It is therefore recommended to shut down non-essential startup applications and disconnect external storage devices to allow the program to focus on internal files. You can also schedule the scan to run at a time when you won’t be using your computer.
First, you’ll need to open Avast and then select 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 allow a full or quick scan, download the most recent definitions, and set the actions to be performed when a threat is discovered.
