As a popular antivirus software, Avast is designed to protect your computer from various types of malware, including viruses, Trojans, spyware, and ransomware. But have you ever wondered what happens to infected files when Avast detects them? Does Avast delete infected files, or does it take a different approach? In this article, we’ll delve into the details of Avast’s file handling policies and explore the different options available to users.
Understanding Avast’s Detection And Removal Process
When Avast scans your computer for malware, it uses a combination of signature-based detection and behavioral analysis to identify potential threats. If a file is detected as malicious, Avast will typically flag it for removal. However, the actual removal process depends on the type of malware and the user’s settings.
Types Of Malware And Their Removal Options
Avast categorizes malware into different types, each with its own removal options. Here are some common types of malware and how Avast handles them:
- Viruses: Avast can usually remove viruses by deleting the infected file or repairing the damaged file.
- Trojans: Trojans are often more complex and may require additional steps to remove. Avast may delete the infected file, but in some cases, it may also recommend a system reboot or a full system scan to ensure all components are removed.
- Spyware: Spyware is typically removed by deleting the infected file or uninstalling the malicious program.
- Ransomware: Ransomware is a type of malware that encrypts files and demands payment in exchange for the decryption key. Avast can detect and block ransomware, but it may not always be able to recover encrypted files.
Avast’s File Handling Options
When Avast detects an infected file, it offers several file handling options to the user. These options depend on the type of malware and the user’s settings.
Automatic Removal
By default, Avast is set to automatically remove detected malware. This means that if Avast detects an infected file, it will delete the file without prompting the user. This option is recommended for most users, as it ensures that malware is removed quickly and efficiently.
Manual Removal
In some cases, Avast may prompt the user to manually remove the infected file. This can happen if the malware is particularly complex or if the user has set Avast to prompt for manual removal. Manual removal requires the user to confirm the removal of the infected file.
Quarantine
Avast also offers a quarantine option, which allows users to isolate infected files without deleting them. This option is useful for users who want to examine the infected file further or who need to recover data from the file.
Repair
In some cases, Avast may offer a repair option for infected files. This option is typically available for files that are damaged but not completely infected. Repairing a file can help restore its original functionality.
Customizing Avast’s File Handling Options
Avast allows users to customize its file handling options to suit their needs. Users can adjust the settings to prompt for manual removal, quarantine infected files, or automatically remove detected malware.
Configuring Avast’s Settings
To customize Avast’s file handling options, follow these steps:
- Open Avast and navigate to the “Settings” menu.
- Click on “Protection” and select “Virus Scans.”
- Under “Scan options,” select the desired file handling option (e.g., “Delete,” “Quarantine,” or “Repair”).
- Click “OK” to save the changes.
Best Practices For Handling Infected Files
While Avast can detect and remove infected files, it’s essential to follow best practices to prevent malware infections in the first place. Here are some tips:
- Keep your operating system and software up to date: Regular updates often include security patches that can help prevent malware infections.
- Use strong passwords: Weak passwords can make it easy for hackers to gain access to your computer and install malware.
- Be cautious when downloading files: Only download files from trusted sources, and avoid opening suspicious email attachments.

What Happens When Avast Detects An Infected File On My Computer?
When Avast detects an infected file on your computer, it will immediately alert you to the potential threat. Depending on the type of threat and the settings you have chosen, Avast may automatically quarantine or delete the infected file to prevent it from causing harm to your system. In some cases, Avast may also offer to repair the file if it is a system file or a file that is essential to the functioning of your computer.
It’s essential to note that Avast’s response to an infected file will depend on the level of protection you have chosen. If you have opted for the default settings, Avast will typically take a more aggressive approach to removing the threat. However, if you have customized your settings to prioritize file repair or manual intervention, Avast will adapt its response accordingly.
How Does Avast Determine Whether A File Is Infected Or Not?
Avast uses a combination of advanced technologies to determine whether a file is infected or not. These technologies include signature-based detection, behavioral analysis, and machine learning algorithms. Signature-based detection involves comparing the file’s code against a vast database of known malware signatures. Behavioral analysis, on the other hand, involves monitoring the file’s behavior to see if it exhibits any suspicious patterns.
In addition to these technologies, Avast also relies on its cloud-based threat intelligence network to stay up-to-date with the latest malware threats. This network allows Avast to share threat data with other users and security experts in real-time, ensuring that its detection capabilities are always current and effective.
What Is The Difference Between Quarantining And Deleting An Infected File?
Quarantining an infected file involves isolating it from the rest of your system to prevent it from causing harm. When a file is quarantined, it is moved to a secure location where it cannot be executed or accessed by other programs. Deleting an infected file, on the other hand, involves permanently removing it from your system.
In general, Avast will quarantine an infected file if it is a system file or a file that is essential to the functioning of your computer. This allows you to review the file and decide whether to restore it or delete it permanently. However, if the infected file is a malicious program or a non-essential file, Avast may delete it automatically to prevent it from causing harm.
Can I Restore A Quarantined File If I Think It Is Safe?
Yes, you can restore a quarantined file if you think it is safe. To do this, you will need to access the quarantine folder in Avast and select the file you want to restore. Avast will then prompt you to confirm that you want to restore the file, and it will be moved back to its original location.
However, it’s essential to exercise caution when restoring a quarantined file. If the file is indeed infected, restoring it could put your system at risk. Before restoring a file, make sure you have scanned it with Avast and verified that it is safe.
How Can I Prevent Infected Files From Getting Onto My Computer In The First Place?
To prevent infected files from getting onto your computer, it’s essential to practice safe computing habits. This includes avoiding suspicious downloads, being cautious when opening email attachments, and keeping your operating system and software up-to-date.
You should also ensure that Avast is configured to scan all incoming files and emails, and that it is set to update its virus definitions regularly. Additionally, consider using a firewall and other security tools to provide an extra layer of protection against malware.
What Should I Do If I Think Avast Has Incorrectly Identified A File As Infected?
If you think Avast has incorrectly identified a file as infected, you should submit the file to Avast’s virus lab for further analysis. To do this, you will need to access the Avast interface and select the file you think is safe. Avast will then prompt you to submit the file to the virus lab, where it will be analyzed by security experts.
In the meantime, you can also try to verify the file’s safety by scanning it with other antivirus programs or by checking its digital signature. If the file is indeed safe, Avast will update its virus definitions to reflect this, and you will be able to use the file without any issues.
