A boot scan is a powerful feature provided by many antivirus programs that can eliminate malware that cannot be eliminated using normal methods. This kind of virus is more difficult to eliminate because it can hide in the boot sector, decrypt files, or even encrypt them. It is crucial that you utilize an antivirus that has the ability to perform a boot scan as this kind of virus isn’t just more difficult to identify but it can also be extremely harmful.
Avast’s Boot Scan is a very effective method of checking for hidden threats. It can detect threats that are typically not detected by runtime scanning, and is capable of removing them without affecting the performance of Windows. However, it can take a while to perform the scan since it has to look through all of your system’s files. It is therefore a good idea to shut down non-essential startup applications and unplug any external storage devices so that the program can focus on internal files. It is also an excellent idea to plan the scan to run at times when you will not be using your computer for any other purpose.
You’ll first need to open Avast and then go to the Settings menu. Once you’re in the settings menu, click the Protection tab, and then click the Boot-Time Scan tile. You can select whether to enable a complete or quick scan, install the most recent definitions, and then set the actions that are taken when a threat has been discovered.
