If a cyber threat manages to make its way into your computer, it can hide in a variety of ways. While most antivirus programs can detect malware through regular scans and real-time protection and boot-time scans, a boot-time scan provides the most thorough protection against stealthy threats.
A boot scan analyzes the system at an early stage, prior to when it starts the Windows operating system. This lets the program detect malware that is hidden, without affecting normal operation. Avast’s boot scan feature has several options for dealing with threats detected during the scan, such as making the files repairable immediately and moving them to the Disease Chest or quarantine, and finally deleting them.
The process of conducting a boot scan could take a long time. To accelerate the process it’s best to block non-essential startup apps and unplug external hard drives or USB devices. This will lessen the likelihood of conflict and allow the scan to concentrate solely on the internal storage. It is also a good idea to reserve the time that you won’t be using your computer for any other work so that the boot scanning can take place without interruption.
To enable a boot-time scanner you must select Settings (the gear icon) within the Avast interface. Select Scan Settings > Protection and then select the Boot Time Scan option. Configure the options according to your preferences, then click OK. The Avast Boot-Time Scan is an effective tool to help you protect your computer from threats and create a more pleasant computer environment.
