Avast Boot Scan is a powerful tool designed to scan your computer for malware and other threats during the boot process, before the operating system and other programs load. This feature is particularly useful for detecting and removing rootkits, Trojans, and other types of malware that can evade traditional antivirus scans. In this article, we will delve into the details of Avast Boot Scan, exploring its functionality, benefits, and how it can help protect your computer from various threats.
Understanding Avast Boot Scan
Avast Boot Scan is a component of the Avast antivirus software, which is a popular and highly-regarded security solution. The boot scan feature is designed to run automatically when you start your computer, scanning your system for malware and other threats before the operating system loads. This approach allows Avast to detect and remove malware that may be hiding in the boot sector or other areas of the system that are not accessible during a traditional antivirus scan.
How Avast Boot Scan Works
When you enable Avast Boot Scan, the feature will run automatically each time you start your computer. The scan process typically takes a few minutes to complete, during which time your computer will be unusable. The boot scan checks your system for various types of malware, including:
rootkits, which can hide malware from the operating system and other security software
Trojans, which can allow unauthorized access to your computer
boot sector viruses, which can infect the master boot record (MBR) or other boot sectors
other types of malware, including spyware, adware, and ransomware
Scan Modes
Avast Boot Scan offers two scan modes: quick scan and full scan. The quick scan mode checks the most critical areas of your system, such as the boot sector and system files, while the full scan mode performs a more comprehensive scan of your entire system, including all files and folders. The full scan mode is more thorough, but it can take longer to complete.

What is Avast Boot Scan and how does it work?
Avast Boot Scan is a powerful tool that scans your computer for malware and other threats during the boot process, before the operating system loads. This allows it to detect and remove threats that may be hiding in the system or trying to load themselves during startup. The scan is performed in a pre-boot environment, which provides a safe and clean space to detect and remove malware without interference from the operating system or other programs.
The Avast Boot Scan works by creating a bootable environment that loads before the operating system, allowing it to scan the system for threats without being affected by the malware itself. This environment is loaded from the Avast program files, and it uses a specialized scanner to detect and remove malware, viruses, and other threats. The scan is typically fast and efficient, taking only a few minutes to complete, and it provides a detailed report of any threats found and removed. This makes it an essential tool for anyone looking to protect their computer from malware and other online threats.
How do I enable Avast Boot Scan on my computer?
Enabling Avast Boot Scan is a straightforward process that can be done through the Avast antivirus program. To enable the boot scan, open the Avast program and navigate to the “Protection” or “Scan” section, depending on the version of the program you are using. From there, look for the “Boot Scan” option and click on it to enable the feature. You may be prompted to restart your computer to complete the process, as the boot scan needs to load before the operating system.
Once you have enabled the Avast Boot Scan, it will automatically run during the next system restart. You can also schedule the boot scan to run at regular intervals, such as daily or weekly, to ensure your computer is regularly checked for malware and other threats. It’s also important to note that the Avast Boot Scan may take a few minutes to complete, during which time your computer will be unavailable. However, this is a small price to pay for the added security and protection that the boot scan provides.
What types of threats can Avast Boot Scan detect and remove?
Avast Boot Scan is designed to detect and remove a wide range of threats, including malware, viruses, Trojans, and other types of malicious software. It can also detect and remove rootkits, which are malicious programs that hide themselves and other malware from the operating system and security software. Additionally, the boot scan can detect and remove boot sector viruses, which infect the master boot record (MBR) or volume boot record (VBR) of a hard drive.
The Avast Boot Scan uses advanced scanning technology to detect and remove threats, including heuristic scanning, which looks for suspicious behavior and patterns, and signature-based scanning, which looks for known malware signatures. This allows it to detect and remove both known and unknown threats, providing comprehensive protection for your computer. The boot scan also provides detailed reporting and logging, allowing you to see what threats were detected and removed, and take further action if necessary.
How long does Avast Boot Scan take to complete?
The time it takes for Avast Boot Scan to complete can vary depending on several factors, including the size of your hard drive, the number of files on your computer, and the type of threats being scanned for. On average, the boot scan can take anywhere from a few minutes to around 30 minutes to complete, although it may take longer in some cases. It’s also worth noting that the boot scan may take longer to complete if it detects and removes threats, as this can require additional processing time.
It’s generally recommended to run the Avast Boot Scan during a time when you are not using your computer, such as overnight or during a lunch break. This allows the scan to run without interrupting your work or other activities. You can also schedule the boot scan to run at regular intervals, such as daily or weekly, to ensure your computer is regularly checked for malware and other threats. This can help to ensure your computer remains protected and secure, without disrupting your normal activities.
Can I use Avast Boot Scan in conjunction with other antivirus programs?
While it’s technically possible to use Avast Boot Scan in conjunction with other antivirus programs, it’s generally not recommended. Running multiple antivirus programs at the same time can cause conflicts and reduce the effectiveness of the scans. Additionally, some antivirus programs may interfere with the Avast Boot Scan, preventing it from running correctly or reducing its effectiveness.
If you want to use multiple antivirus programs, it’s recommended to use them in a layered approach, where one program is used for real-time protection and another program is used for on-demand scanning. For example, you could use Avast as your primary antivirus program and use another program, such as Malwarebytes, for on-demand scanning. This can provide comprehensive protection for your computer, without causing conflicts or reducing the effectiveness of the scans.
How do I interpret the results of an Avast Boot Scan?
The results of an Avast Boot Scan are provided in a detailed report that shows what threats were detected and removed. The report will typically include information such as the name of the threat, the location of the threat, and the action taken to remove the threat. You can use this information to take further action, such as removing any remaining malware or taking steps to prevent future infections.
The Avast Boot Scan report will also provide information on any threats that were not removed, such as threats that require manual removal or threats that are still active. In these cases, you may need to take additional steps to remove the threats, such as using a specialized removal tool or seeking the help of a professional. The report will also provide recommendations for how to prevent future infections, such as updating your operating system and software, and avoiding suspicious websites and downloads.
Is Avast Boot Scan free to use, or do I need to purchase a subscription?
Avast Boot Scan is a feature that is included with the Avast antivirus program, and it is available for free to all Avast users. However, some advanced features, such as scheduled scanning and detailed reporting, may only be available to users who have purchased a premium subscription. Additionally, some features, such as real-time protection and automatic updates, may require a premium subscription to function.
If you are using the free version of Avast, you can still use the Avast Boot Scan to detect and remove threats, but you may not have access to all of the advanced features. To get the most out of the Avast Boot Scan, it’s recommended to purchase a premium subscription, which will provide you with access to all of the advanced features and provide comprehensive protection for your computer. The premium subscription will also provide you with priority customer support, automatic updates, and other benefits.
