Does Avast Delete Infected Files & How To Recover Them

According to AV-Test, Avast is the second-best antivirus for Windows. And, that’s why it is one of the most popular & widely used antivirus software. You can guess Avast’s dominance knowing the fact that it acquired AVG Antivirus in 2016.

As good as Avast is, it is not perfect and not easy to operate for beginners. Like most antivirus, it too can sometimes detect certain files as false positives. It basically means that the file isn’t actually a virus but antivirus software still flags it as such. This results in Avast deleting your file from the location without asking.

If you too are experiencing a similar problem & now wondering if Avast has deleted your infected file permanently then this guide is for you.

Does Avast Antivirus Automatically Delete Infected Files?

The answer to this question is a Yes & a No. To know why the answer to the question is so diplomatic we need to know how Avast works.

Whenever Avast detects a potential malware or virus it tries to disinfect the file. If it is unsuccessful then Avast moves the file to the quarantine folder. However, sometime Avast is unable to disinfect the file or move it to the quarantine folder. In that case, Avast will delete your file permanently to protect your computer.

By design, this protects the user from worse-case scenarios which could be malware or ransomware hijacking your computer.

However, permanent deletion of files happens on rarest of the occasions. Most of the time files can be recovered from the quarantine folder.

  • To retrieve your file, you can either select, the “Restore” or the “Restore and add an exception” option. Selecting the Restore option will restore your file to the same location from where it was deleted. However, the file can be once again moved by the Avast to the quarantine folder. So if you are 100% sure it’s not a virus then click on Restore and add exception option. This will prevent Avast from quarantining the same file ever again. Go back to the location of the file it should be restored there now.

How To Restore Files Deleted By Avast Antivirus

If you can’t find your file in the Quarantine option of the Avast then I would recommend using the Stellar Data Recovery Software. This is a data recovery software that allows users to recover their permanently deleted data.

There is plenty of data recovery software available but I found this one to work consistently well. I was even able to restore deleted files on SSDs. You can check my in-depth Stellar data recovery review if you want to know more about all the features of the software.

Besides consistent reliable performance, another reason I recommend using Stellar Data Recovery is that it also offers free file recovery of up to 1 GB. So unless you have lost videos or a bulk of high-quality images, you won’t need to spend a single penny.

Let’s start with Data Recovery Process.

  • First, download & install Stellar Data Recovery software on your computer.
  • Next, launch the application Stellar Data Recovery. On the home screen, the data recovery software will ask you to select which kind of file you want to recover. Depending on the format of the file deleted by Avast select the relevant file type. For example: if the file deleted is an image then uncheck all the other options & select Photos. If you’re ascertain about the file type or it’s not mentioned then select the All Data option & click on Next.
