What Does a Boot Scan Do?

When a cyber-attack makes its way into your computer, it could be disguised in a variety of ways. Many antivirus programs can identify malware via regular scans, or real-time protection. However the boot time scan is more thorough and can detect threats that are hidden.

A boot scan checks the system at a very early stage, before it launches the Windows operating system. This lets the software identify malware that is hidden, without affecting normal operations. Avast’s Boot Scan feature offers a variety of options to handle threats found during the scan. These include repairing the files immediately, moving them to the Disease Chest or quarantine area, or eliminating them.

It can take a while to run a boot check. To accelerate the process it’s best to disable non-essential startup applications and disconnect external hard drives or USB devices. This will reduce the chances of conflict, and allow the scan only to focus on internal storage. It is also an ideal idea to allocate some time during the day when you won’t be using your computer for other activities, so that the boot process can run without interruption.

To enable a boot scan, open the Avast user interface, and then click Settings (the gear icon). 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 a powerful tool to help protect your system from dangers and to provide a more efficient computer environment.
