The Avast anti-virus keeps your computer safe by deleting malicious or suspicious files that interfere with its operations. It wipes out these data mostly without your authorizations and puts out an error message saying you can’t restore them. Tragic right? But do not be alarmed as nothing is permanently lost in a computer.

Your file can be restored from Avast by going through the Avast virus chest; it stores the suspicious files. To access the Avast virus chest, tap the orange-colored virus logo. Select the “virus chest”, then click and restore the deleted data. 

The avast anti-virus may seem brutal in judgment, but it is actively doing its job. Nonetheless, we recommend that you scan recovered data as it may contain malware. Read through this article to learn about the different ways to restore Avast deleted data.

Avast This File Cannot Be Restored

Avast anti-virus sends the error message this file cannot be restored because it sees your data as a threat. However, the Avast notification can be due to false detection. Here are five different techniques to recover your data.

Avast Virus Chest

If Avast deleted your files without warning, you could use this technique to restore them. You can access the chest using two ways;

Method 1

1.Right-Click on the Avast anti-virus icon
2.Open the system menu and click on the virus chest.

Method 2

  1. Click on the Avast icon and open the User menu.
  2. Select the Protection option on the menu 
  3. Tap on the virus chest 

We recommend method one as its faster and easier to use. However, you can try both ways and choose your preferred one.

Reopen The Chest

At the first trial, the virus chest may not respond or recover the file in some situations. However, try closing the Avast app, reopening it, and then confirm if you can restore your deleted data.

Repair Your Anti-Virus

If your Avast is functioning abnormally and would not let you restore your data, repair it. To do this, follow the instructions below.

Step 1: Search for the control panel via the “Taskbar.”

Step 2: Open the control panel and select the program on the menu.

Step 3: Tap “uninstall a program”

Step 4: Search for Avast, click on it and tap repair

Install Avast

If you have tried the methods above and it still does not respond, then your avast Anti-virus is the issue. You would need to delete and re-install it back on your personal computer. Here are the steps to help you.

Step 1: Search for the control panel in your Taskbar 

Step 2: Click on it and open the “program” setting and click on “uninstall a program.”

Step 3: Select and open the uninstall utility setting, authorize “reboot to safe mode.” It will take out the remaining data and “registry entries”.

Step 4: Reboot the computer and install Avast.

Send A Complaint

Send a complaint to Avast about your malfunctioning anti-virus. Report how it detected and deleted a false threat. Here are two possible strategies you can adopt.

Open the Avast anti-virus chest using the methods above. Right-click on the Avast and select the option “submit to threat lab”. Alternatively, forward a mail and attach a copy of the file if available and send it to Submit@Virus.avast.comIt would be best if you typed “undetected malware” as the subject. After sending the email, Avast would reply to you with an adequate response to solve your issue. 

How Do I Restore An Avast Quarantined File?

In case Avast anti-virus continuously deletes important data without asking your permission, you can restore them in two ways.

  • Restore via third party app
  • Restore via Virus chest

Restore Via Virus Chest 

Virus chest is where Avast keeps possible malicious folders. It extracts the file from your computer and locks it away in the virus chest. The reason for this action is to keep your computer safe from attack and potential threats.

Open the virus chest and restore the files with the following instructions; 

Open the Avast icon, click on “Protection”, and go to the virus chest. Click on the file and select restore.

Restore Via Third Party App

Some people feel that they have a slim chance of restoring Avast deleted files. However, some third party app can retrieve such files in few steps. Here, we used the EaseUS recovery app and DiskInternals Uneraser app as examples of how you can use third-party apps to recover the file.  

  • Easeus

Step 1: Click on the previous location of the file. If the file was previously in the music folder before the anti-virus scan, select that as its location.

Step 2: Allow the third-party app to perform a scan to locate the Avast deleted folder. It would bring up a pop-up menu of all previously deleted files. If it does not show, search through Lost files. 

Step 3: Tap the Filter setting to locate the files you lost faster. Finally, select the Recover option to bring back your files.

DiskInternals Uneraser App.

The DiskInternals Uneraser app is efficient but would require obtaining a licence to export your restore data.

Step 1: Install and run the software on the affected computer.

Step 2: As you run it, it enables the ”recover wizard” program on your PC 

Step 3: Click on the storage you want to scan. If it is external storage, set it to be connected before the scan.

Step 4: Click on the file type the program should detect 

Step 5: Perform a scan

Step 6: Find the files, but to export them, you need a license and then save your data.

Why Does Avast Anti-Virus Consider My File As A Threat?

The Avast anti-virus extracts and locks any file that its interactions cause the computer operation to change. Even as the file is not a real threat, the Avast would treat as one. It further puts up an error message refusing to allow you to restore it. As we can guess, your anti-virus is only fulfilling its objective, and you would consider it useless if it acts otherwise. Yes, sometimes the files are not threats but false alarms. One of the techniques to prevent this issue is to employ the file exclusion method.

Exclusion Method

To execute this technique and release your quarantined files, follow these instructions.

  • Open the Avast anti-virus program. 
  • Tap the menu settings
  • Open the setting 
  • Go to the exclusion folder and open it.
  • Click on the advanced menu to access the folder configuration setting. 
  • Select file path and choose URL

It is valid to point out that although Avast sometimes deletes a false alarm threat folder, it effectively protects your computer. The anti-virus may just needs a reboot or repair procedure from time to time. As mentioned above, nothing is lost, even when you cannot see it.  

Avast Virus Chest

The Avast chest is a space set aside by the anti-virus to store malicious data. It gives you access to forward such files to the Threat lab to be further scrutinized by the avast team. Files stored in the chest have no possible permission to interact with your computer. 

The avast anti-virus transfers the potentially malicious file to chest in these ways 

  • When you set up your anti-virus to scan. It starts and observes any file that is influencing the computer operating system
  • If your anti-virus protection shield is effective

In these two situations, the avast will take immediate actions to block and protect. It will result in files extracted and locked in the chest.

Access Into Chest

You can open and make changes in the chest in two ways.

  • Avast antivirus> Protection> Virus chest
  • Right-click on the Avast setting in the menu tray and tap virus chest

The Avast Antivirus program will actively prevent and block malware and virus from your computer. If you restore a potentially malicious file and discover it is a threat, you can manually add them back to the virus chest.

  1. Open the chest and select the add file option
  2. Identify the folder you want to add
  3. Select open, and add the file to the list of files in the Avast virus chest.

You can also send the file to the threat. The files you should look out for are

  • Malware: files you suspect to be malware; scan them to be sure. 
  • False alarm: files identified by Avast as malicious, yet you think they are safe data.


The Avast anti-virus carries out interval scans and deletes potential risks and files. It performs this to protect your computer from attacks. You can restore the deleted and locked data from the anti-virus chest. You can also involve third-party apps to help you recover your files.
