What Does a Boot Scan Do?

Cyber threats can be hidden in many ways. Many antivirus programs are able to detect malware by running regular scans or real-time protection. However the boot time scan is more thorough and can identify threats that are not obvious.

A boot scan is a short review of your computer prior to Windows starts. This allows the software to detect malware that is hidden, without affecting normal operations. Avast’s boot scan feature offers a number of options for dealing with the threats discovered during the scan, such as making the files repairable immediately, moving them to Disease Chest or quarantine, or deleting them.

It may take a while to run a boot check. To speed things up it’s a good idea to disable non-essential startup applications and unplug external hard drives or USB devices. This will decrease the chance of conflict and allow the scan only to focus on the internal storage. It is also a good idea to schedule the time that you will not be using your computer for any other tasks so that the boot scanning process can be completed without interruption.

To enable a scan that is based on the time of the boot, select Settings (the gear icon) in the Avast interface. Select Protection > Scan Settings and then check the Boot Time Scan option. Set the options to your preferences, and then click OK. The Avast Boot-Time Scan is an effective tool to help you protect your computer from malicious threats and to provide a more efficient computer environment.
