What Does a Boot Scan Do?

When a cyber-attack makes its way into your system, it may hide in a variety of ways. While several antivirus programs are capable of detecting malware with regular scans and real-time protection, a boot-time scan offers an even more thorough defense against the most elusive threats.

A boot scan analyzes the computer system at an initial stage, before it begins the Windows operating system. This lets the software identify hidden malware without disrupting normal operations. Avast’s Boot scan feature offers several options to handle threats found during the scan. These include repairing the files immediately, moving them to the Disease Chest or quarantine area, or deleting them.

It may take a while to run a boot test. To accelerate the process it’s recommended to block non-essential startup apps and unplug external hard drives or USB devices. This will reduce the chances of conflict and allow the scan to focus on the internal storage. It is also a good idea to schedule some time during which you will not use your computer for any other activities so that boot scanning process can be completed without interruption.

To enable the boot scan, open the Avast user interface, and then click Settings (the gear icon). Select Protection > Scan settings and select the option for a Boot-Time Scan. Adjust the settings according to your preferences, and then click OK. The Avast Boot-Time Scan is a highly effective tool to help you safeguard your computer from malicious threats and have a smoother computing environment.
