In today’s digital age, ensuring your computer is free from viruses and malware is more critical than ever. Avast, one of the leading antivirus software programs globally, offers an efficient solution to combat these threats. One of its standout features is the boot scan, which allows you to detect and eliminate malware before the operating system loads. In this article, we will explore how to perform a boot scan with Avast, highlighting its benefits and providing a step-by-step guide to enhancing your device’s security.
Understanding The Boot Scan Feature
Before we delve into the steps for conducting a boot scan with Avast, let’s understand what a boot scan is and why it’s essential.
What Is A Boot Scan?
A boot scan is a comprehensive examination of your system that runs prior to the operating system’s startup. It specifically targets the boot sector and critical system files which are often the hiding places for malware. Since these files are loaded before your operating system, many malware types can evade detection from traditional scans conducted once the system is up and running.
Why Choose A Boot Scan?
There are several compelling reasons to use a boot scan:
- Early Detection: Performing a boot scan allows Avast to identify and neutralize threats before they can affect your system’s performance.
- Comprehensive Protection: It scans areas that typical scans might overlook, increasing your computer’s overall security posture.
Preparing For A Boot Scan With Avast
Before starting your boot scan, ensure your Avast software is updated to the latest version. Always keep your antivirus software up to date for optimal protection against new threats.
Checking Your Avast Version
- Open Avast on your PC.
- Navigate to the top-right corner and click on the menu (three horizontal lines).
- Select “Settings.”
- Click on “About” to view your current version. If an update is available, you’ll see an option to update it.
How To Back-Up Your Files
Backing up your files before running a boot scan is another crucial step. While it’s uncommon for the scan to remove files that are not threats, having a backup protects you from unexpected data loss.
- Use a cloud storage service or an external hard drive.
- Ensure that all vital documents, photos, and applications are securely backed up.

What Is A Boot Scan In Avast?
A boot scan is a type of antivirus scan that runs before the operating system fully loads. This allows the scan to detect and eliminate viruses and malware that may be embedded deep within the system or are difficult to remove while the operating system is running. By performing a boot scan, you can ensure that harmful programs are removed before they have a chance to execute and infect your files.
Avast uses boot scans to ensure that your computer starts up clean and is free of infections that could compromise your system’s security. This is particularly important because some malware can hide in the system or reproduce, making it challenging to eliminate with standard scans. The boot scan significantly increases the chances of deleting these malicious programs.
How Do I Schedule A Boot Scan With Avast?
To schedule a boot scan with Avast, open the Avast antivirus application and navigate to the “Scan” section from the main dashboard. Here, you will find options for various types of scans. Select the option for boot scan and click on the settings to choose a specific time for the scan to occur. You might find the feature under the “Advanced” settings or within the scheduling options.
Once you have set your desired time, make sure to save your changes. The boot scan will initiate when you restart your computer at the scheduled time, allowing for an effective scan without interference from other processes. This scheduling feature helps ensure that you don’t forget to run important scans regularly.
Can I Run A Boot Scan While My Computer Is On?
No, a boot scan cannot be run while your computer is already on. The essential aspect of a boot scan is that it must be executed before the operating system starts fully loading. This allows Avast to access system files and disk areas that may be restricted while the OS is running. Thus, you need to restart your PC in order to initiate the boot scan.
Instead, you can set up the boot scan in advance, so it runs the next time you restart your computer. When prompted, simply agree to the boot scan, and it will automatically commence the next time the machine powers on. This process ensures that any potential threats are detected and dealt with before they have an opportunity to harm your system.
How Long Does A Boot Scan Take With Avast?
The duration of a boot scan with Avast can vary based on several factors, including the size of your hard drive, the number of files, and the overall performance of your computer. Typically, a boot scan can take anywhere from a few minutes to an hour to complete. If your system has a large amount of data or if there are many potential threats, it could take longer.
During the boot scan, Avast will thoroughly check the system for harmful files and malware. While it may take some time, it’s a crucial step in ensuring your computer’s safety. It’s also worth noting that even if the scan takes longer than expected, you can monitor its progress through the on-screen notifications that will inform you of the scanning status.
What Should I Do If Avast Finds A Threat During A Boot Scan?
If Avast detects a threat during a boot scan, it will typically provide options for how to handle the detected malware or potentially unwanted programs. Common options include “Quarantine,” “Delete,” or “Ignore.” It is generally advisable to quarantine the detected threats first, allowing you to analyze them later without letting them pose any immediate danger to your system.
After the boot scan is complete, you can revisit any quarantined files in Avast’s quarantine area. From there, you can decide whether to delete them permanently or restore them if they are false positives. Always take the time to review any detected threats to ensure that you are making informed decisions regarding your system’s security.
Is A Boot Scan Necessary If I Already Run Regular Scans?
While regular scans are an essential part of maintaining your computer’s security, boot scans serve a distinct role that can enhance your protection. Regular scans typically check for virus signatures existing in files that are currently accessible. However, some malware can embed itself deep within your system and may operate unnoticed while your OS is running.
Considering the sophistication of many modern threats, performing boot scans from time to time can help uncover these hidden infections. This preventive measure, combined with regular scans, forms a comprehensive security strategy that helps safeguard your PC against all forms of malware and vulnerabilities.
Can Boot Scans Fix Issues Related To System Performance?
Boot scans primarily focus on identifying and eliminating malware, which can be a significant factor affecting your system’s performance. If your computer is running slow or experiencing performance issues due to malware or viruses, a boot scan can help rectify these problems by locating and removing the threats that are contributing to the decline in performance.
However, it’s important to recognize that not all performance issues stem from malware. Other factors, such as insufficient memory, software conflicts, or hardware limitations, might also contribute to sluggishness. While boot scans can certainly help with virus-related performance issues, it may be necessary to explore additional diagnostic tools or system optimizations to address other underlying problems affecting your PC’s performance.
